S ome musical artists like to get big-name actors to star in their videos and drum up hype around a release.

Others will lean into relatively unknown talents, providing them their big breaks.

Either way, it's made for some very iconic videos over the years. Some, many people almost forgot even happened...

The year was 2009 and Australia's own pop princess Kylie Minogue was setting her sights on world domination after conquering the British and Middle Eastern market.

And what better market for a popstar to target than the dramatic, star-studded industry of Bollywood?

T he Can't Get You Out Of My Head singer collaborated with legendary Oscar-winning composer A. R. Rahman for the "item song" (the most important song in a Bollywood movie, usually featuring a big name) of 2009 film Blue.

Not only did she lend her voice, she also appeared in the music video, dancing and singing along with Bollywood superstar Akshay Kumar.

The song remains an ear worm 16 years on, with the original music video racking up 11 million views.

T hough she never actually performed the song in India, the now-56-year-old says it has always been on her bucket list.

In a recent interview with The Times of India, the superstar said, "One day I will perform Chiggy Wiggy in India. That's my mission. I'll see if I can make it happen."

She also recalled working on the project all those years ago, doing dance rehearsals with renowned director and choreographer Farah Khan and even having lunch Kumar and his family

"Mumbai was a complete whirlwind! Just to be on a Bollywood set was kind of crazy, in the best way. It was such a warm welcome.

"...I only wish that I had been back sooner...Maybe Akshay will invite me over for lunch again."

A young Lady Gaga has been spotted in AC/DC's Stiff Upper Lip music video peering over her shoulder at the camera.

The singer made a recent appearance on the Apple TV's A Carpool Karaoke Christmas Special, where she opened up about her love of rock band.

Lady Gaga told Brian Johnson, "You wanna hear something funny? I was in the Stiff Upper Lip video. I was 17 and I was an extra in the back."

"I was headbanging and they were like, 'hmmm. Don't head bang, we want it to be modern.' And I was like, 'no, there's only one move that I can do.'"

Alicia Silverstone was the main girl in Aerosmith's Cryin', released a few years before her big break in Clueless.

She was cast after the video's director saw her in the movie Crush, and thought she'd be perfect for the video.

In it, she's seen getting her belly button pierced, a scene which is credited with helping make them a trend in the '90s.

Silverstone was then cast in two more Aerosmith videos, Amazing and Crazy, which made her a household name and boosted her acting career.

A young Mila Kunis can be spotted in the Aerosmith video for Jaded, released in 2001.

The song, about a girl who is jaded by the glitz and glam of her life, is said to be about Liv Tyler, though Kunis was chosen to portray her in the video.

"It was a huge honour to work with them," she told the New York Post at the time.

"What's so rad about it was that Steven Tyler actually introduced himself to me. And it was so cool because he's so down-to-earth. There's not one person on this planet who doesn't know who he is."

J essica Simpson burst onto the music charts in the late '90s, but another star was hot on her heels.

That star happened to be her younger sister Ashlee, who had a small appearance in one of her big sis' music videos years before carving out her own path and becoming a household name in her own right.

If you look at this still from the 2000 video for I Think I'm In Love With You, Ashlee is pictured next to her famous sister, wearing a red tank top.

The future pop-rock star served as a backup dancer for her sister before she hit the charts with her own solo music in 2004.

Before her own career got off the ground, Jennifer Lopez starred in Janet Jackson's music video for her 1993 track That's the Way Love Goes.

She later spoke about how Madonna and Jackson's videos were inspirations for her own career. "They were my inspirations to even get into the music business, to do what I did," she said. "Their videos inspired me to do the videos that I did."

Channing Tatum's first-ever on-screen role was in a music video for Ricky Martin's song She Bangs when he was 18.

It's a blink-and-you'll-miss-it cameo: Tatum can be glimpsed as a shirtless bartender during a club scene.

Before she was a megastar, Kim Kardashian was smooching Pete Wentz in front of the cameras for Fall Out Boy's video for thnks fr th mmrs.

This was back in 2007, when she was just a socialite – and months before her reality show launched.

In 2018, Pete told People: ​"I stay in touch with her a little bit – just emails here and there. I ran into her, and she was probably the nicest person ever. She's exactly the same as she was then, except she's, like, a trillion times more famous."

Courteney Cox's first on-screen appearance was in Bruce Springsteen's Dancing in the Dark music video.

She auditioned for the role, and despite having no formal training, won out over other professional dancers.

"I thought I was in the wrong place," Cox later told Howard Stern about going to the audition. "I was like, I don't know what they're doing, but I can't even bend my leg ... I think that's what they wanted, a fan that just couldn't believe it."

Angelina Jolie was the main star in the Rolling Stones' Anybody Seen My Baby?, released in 1997. She plays a stripper who leaves mid-performance and wanders around the streets of NYC.

The band's lead singer, Mick Jagger, pursued Jolie romantically for a while after the video was filmed, but she rejected him. At the time, she was married to Jonny Lee Miller.

The rock star kept calling Jolie, and according to Christopher Anderson's book, Mick: The Wild Life and Mad Genius of Jagger, she relented and went with him to a party.

But halfway through the "date", he reportedly disappeared.

Before he was a bona fide Marvel star, Jeremy Renner had a role in the P!nk video Trouble, as a sexy sheriff the singer tries to seduce.

In 2017, the actor posted a throwback photo to hi s Instagram from the set of the music video. "Hey @P!NK remember this trouble? Lol," he captioned the pic.

Tom Hanks famously made a very random cameo in Carly Rae Jepsen's video for I Really Like You in 2015.

It all came about because they have mutual friends.

"I was at dinner with friends of ours who work with Carly and they said, 'We were maybe going to ask you if you'd want to do this thing,' and I literally had a beer in my hand and I said, 'Yeah sure I'll do it,'" Hanks told ET.

"And that was it! Next thing I know, boom! Carly Rae Jepsen video."

When True Blood actor Alexander Skarsgård starred in the Lady Gaga video for Paparazzi, he had no idea who the singer was.

"I was in LA shooting one of my first jobs which was season one of True Blood," Skarsgård later explained to Jimmy Fallon. "But it was the very beginning, so the show hadn't aired yet. And my friend, Jonas Akerlund, a Swedish guy, he's a director, and he was gonna direct the music video."

"He called me and asked me if I wanted to play the boyfriend. I said, 'Boyfriend?' I didn't know who the girl was, Lady Goo Goo."

After years of comparisons between the two stars, Rupert Grint popped up in Ed Sheeran's video for Lego House – as a fan being hunted down by security.

Sheeran said he'd always wanted to get Grint to play him in a music video, but the Harry Potter actor wasn't convinced.

It wasn't until Sheeran befriended Tom Felton – who played Draco in the Potter films – and asked him to convince his co-star to sign on to the idea.

"He actually told me the other day that it wasn't as open [and] shut as I thought it was," Sheeran revealed on a podcast in 2021. Like he really had to convince Rupert's agent that this was a good thing."

Tyra Banks has a cameo at the end of Michael Jackson's video for the 1991 song Black or White.

"I forgot the dance moves, so I'm the only one in the video doing something wrong and sticking my tongue out," she later told Entertainment Weekly.

Macauley Culkin also appeared in Michael Jackson's 11-minute video for Black or White.

Culkin is now godfather to Jackson's daughter Paris.
