Lana Del Rey‘s gone from singing “Diet Pepsi” in her car to on her stage at Wembley Stadium — inviting opener Addison Rae back out to perform alongside her at her July 3-4 London concerts.

Lana took verse one of Addison’s single — with its lyrics about her ripped blue jeans, cherry red lips and body that’s “a work of art you’d die to see,” all of which wouldn’t sound out of place in the earlier years of LDR’s own discography — and Addison joined in on the “untouched, XO, young lust, let’s go” pre-chorus, with the two vocalists coming together on the hook: “When we drive in your car, I’m your baby/ Losing all my innocence in the backseat/ Say you love, say you love, say you love me/ Losing all my innocence in the backsеat.”

“Sooo good!!” Lana herself commented on a video of their duet that had been posted by a fan on Instagram after the London gigs.

The pair also sang Lana’s new ditty “57.5,” an earworm she’d debuted at Stagecoach that walks the line between owning her brand of fame and finding the humor in just how many millions of fellow melancholic music lovers must be out there — with a nod for country fans to catch.

“I still talk to Jesus, yes/ But I still call up psychics when I need advice/ I still fly commercial/ You need an autograph? S—, I don’t mind/ If you want the secret to success, I suggest showing up in a Ross dress,” Lana sang, referencing the time she told red carpet correspondents she bought her Grammys dress at the mall, before both artists launched into the campy, catchy chorus: “I got 57.5 million listeners on Spotify/ Roger Miller made ’em laugh/ I guess some folks still like to cry/ I ain’t got a man, but maybe one of them is a fan of mine/ In that 57.5 million listeners on Spotify.”

“@honeymoon I will never forget this,” Addison wrote on Instagram, recapping her momentous weekend sharing the stage with Lana. “Thank you so much to the most beautiful divine woman, heart, soul, mind… Lana. I am the happiest and luckiest girl on earth. Being next to you is spiritual.” Ladybug, infinity and bouquet emojis were used in Lana’s honor.

“Thank you @honeymoon. You are forever,” she added in another post from London, topping off this comment with a swan emoji.

Before announcing Addison as an opening act or heading overseas for tour, Lana uploaded an Instagram Story that captured the sweet reaction she’d had upon vibing to “Diet Pepsi” while driving her car, hand over her mouth and eyes tearing up.

“Diet Pepsi” was released as the first single from Addison’s eponymous debut album, Addison, and was the influencer-turned-pop newcomer’s first to chart on the Billboard Hot 100, in fall 2024.

By the time of Addison the album’s release last month, the set saw a No. 4 launch on the Billboard 200.

Addison Rae was among a trio of opening acts announced just ahead of Lana Del Rey’s U.K. and Ireland stadium run, a short stint of five shows. While the “Headphones On” singer got the gig with Lana in London, London Grammar performed in Cardiff and BANKS joined the tour in Glasgow, Liverpool and Dublin.

It’s a wrap for Lana’s tour, leaving fans to now await the unveiling of her 10th studio album, formerly known as Lasso and The Right Person Will Stay at different points of time. Its original release date was delayed to an as-yet-unknown date, and the project’s current working title has not been publicly confirmed, but fans have so far heard the songs “Henry, Come On” and “Bluebird,” both available on streaming services — as well as live renditions of “Stars Fell on Alabama,” “Quiet in the South” and the aforementioned “57.5,” all assumed album tracks.

Addison has her debut headlining tour to look forward to, with dates across select cities in Europe, North America and Australia spanning August through November.
