Rafael Nadal says images of him promoting investment schemes are AI scams.

The King of Clay warned fans and followers not to fall for deep fake images of him purportedly supporting investment platforms.

“I’m sharing this unusual but necessary message. My team and I have discovered that artificial intelligence — generated videos are being spread on some platforms, in which a figure imitates my appearance and voice,” Nadal posted on social media. “These videos falsely attribute investment advice or proposals to me. This is deceptive advertising.

“Please be cautious: I have never created or endorsed such messages. Thank you all for your attention and support.”

Former world No. 1 Nadal was in the news last week when rival Roger Federer told CNBC he’d love to do a Fedal Exhibition Tour with Nadal at some point in the near future.

The 44-year-old Federer, who looks extremely fit, says he’s been playing tennis fairly frequently and would love to reunite with old rival Rafa.

“Why not? I love Rafa,” Federer told CNBC. “I played four hours of tennis the other day in LA—here in San Francisco, sorry—and then in LA also another hour and a half. So before that I’ve been playing a lot.

“I’ve been trying to keep in good shape. And I know that Rafa is totally open to maybe playing some tennis. It sounds terrible, seniors tennis, to us but maybe we can create a tour like a Fedal Tour or something like that. I mean it would be cool.”
