The actor took the dip at Soho Beach House in Miami, Florida during a break from filming Fast 8 in Atlanta, Georgia.
It's more than Eastwood's bod that's got people talking, however. Rumors have been swirling about the 30-year-old actor's relationship with Victoria's Secret model Adriana Lima since they were spotted flirting at the New York City restaurant Catch on Wednesday.
An eyewitness told ET that the two dined together in a group and were being "really affectionate," with Eastwood's arm around Lima "the whole time."
Lima's reps, however, denied that Eastwood was even in attendance, while a source close to the Suicide Squad star confirmed to ET that he was in New York and did eat at the restaurant but the claims about him and Lima are not true.
So there you have it -- officially not dating, but Eastwood may have the ability to be in two places at once.
Eastwood is playing the protégé to Michael Douglas' Mr Nobody character in the next installment of the Fast and Furious franchise.
