Serena Williams recently received unexpected support in favor of a comeback from a friend. Formula 1 legend Lewis Hamilton called himself a 'massive' supporter of the American tennis icon and hoped to see her on the court again.Hamilton recently concluded his first-ever season with Ferrari in F1. The record seven-time champion, who is worth $450 million (according to CelebrityNetWorth), completed the 2025 season in sixth without any podium finishes. After the final race in Abu Dhabi, he was asked if he would like to see Williams back on the court."I’d love to [see it]," he said (via Tennis365). "I keep telling her to come back."Further, he said he was honored to be a friend of the 23-time Grand Slam champion."Massive, massive supporter of her. She’s the greatest of all time, such a legend. She was at one of the races just recently. A dear friend as well, which I’m really honoured by," he added.Earlier this month, Williams' name appeared on the official testing list of the International Tennis Integrity Agency (ITIA), and speculation erupted that the 44-year-old might be planning a return to the pro tour.Almost immediately, she publicly shut down the rumors. On her social-media account, Serena Williams wrote:"Omg y’all I’m NOT coming back. This wildfire is crazy."Registering for testing is a prerequisite for any potential return, but also that being in the pool doesn’t guarantee a comeback."It would only be for something truly meaningful" - Former WTA pro opens up about Serena Williams' chances of a comeback on tourSerena Williams at the 2022 US Open - Source: GettyFormer Top 10 player Anna Chakvetadze spoke about the hypothetical situation where Serena Williams made a return to the WTA Tour. The former rival of the American said that it would be "very special" for tennis if she returns."Serena is a legend of our sport and one of the greatest champions in history. If she ever decides to return, it would obviously be something very special for tennis. In individual matches, especially on the biggest stages, she could still look very competitive," Chakvetadze said.The Russian also said that only "something truly meaningful" would make the 23-time Grand Slam champion return."The key question is how the body responds to that kind of physical load over time. If she does come back, I’m sure it would only be for something truly meaningful to her. She has achieved everything in tennis, and her legacy is already untouchable," Chakvetadze concluded.Williams retired from the sport in 2022 after playing at the US Open under the guidance of Rennae Stubbs. She has since focused on her life with her two daughters and her several businesses.
