Tennis fans are buzzing—and not just about rankings. Emma Raducanu and Carlos Alcaraz, two of the sport's brightest young stars, have sparked rumors that their bond may be more than just professional.

The pair are set to join forces in the mixed doubles at the US Open this August, but their off-court chemistry is what’s drawing headlines.According to multiple reports—including Daily Mail and The Sun—Emma was spotted cheering Carlos on at the Queen’s Club Championships, not once but twice: on Thursday and again on Saturday, the day before he won the title. Witnesses claim her car pulled in just minutes after Carlos arrived with his team.

Inside, the pair were seen laughing, chatting, and appearing incredibly at ease around each other. “It’s been the talk of Queen’s,” one source revealed.

“He was even seen at her hotel earlier in the week.”

Emma has addressed the rumors with a coy smile and the classic line: “We’re just good friends.” But her words, while diplomatic, haven’t convinced fans or the media. During a BBC interview after her second-round Wimbledon win, the topic took an unexpected twist when she was told pop star Olivia Rodrigo had been in the Royal Box watching her.

Emma laughed and replied, “She’s got some great heartbreak songs... If you’re ever going through it, she’s the one.

” Then came the punchline: “I wouldn’t know though, of course not.” It was a subtle but telling moment—flirtatious, fun, and very aware of the speculation swirling around her.The British starlet has been relatively private about her relationships. Her last known romance was with billionaire heir Carlo Agostinelli, a former footballer and the son of businessman Robert Agostinelli.

The two appeared together at high-profile events like Paris Fashion Week and enjoyed luxe getaways in Greece and Mexico before quietly parting ways and unfollowing each other online.But with Carlos, things feel different. Their connection dates back to their breakout tournaments in 2021—Emma’s fairy-tale run at Wimbledon and US Open, and Carlos’s rise through the ranks. “We’ve known each other for years,” she shared.

“Wimbledon 2021 was the first time I started getting to know him… we kept in touch through the US Open. It’s nice to still have that bond.”

As for Carlos, he's made no secret of the fact that he’s single—and open to love. Speaking candidly in an interview earlier this year, the 21-year-old said: “No, I am single. I am looking for someone. It can be difficult as a tennis player to meet the right person because you are traveling all the time.” Despite a hectic tour schedule, the reigning French Open champion has still found time to dominate on court, entering the Round of 16 at Wimbledon this Sunday, July 6, as the two-time defending champion.While Emma’s denials appear firm, the timing of their doubles partnership, their shared past, and their ease around each other continue to fuel speculation.
