Gabrielle Union Turns Up the Heat in Cheeky Red Bikini

Gabrielle Union might be on vacation, but her body never takes a day off … just look at these smokin’ hot pics of the enchanting actress on a Miami beach.

The star took her talents — and her seemingly endless legs — down to South Beach over the weekend … where she enjoyed the sun, surf and sand with her Hall of Fame husband, Dwyane Wade.

Gabrielle stunned in a bright red two-piece that left to the imagination … showing off nearly every inch of bodacious bod.

She wore a bandana over the luscious locks … and alternated between dipping into the ocean blue and heading back up to dry land for some much-needed rays.

Unclear if this is a birthday trip for the star … though the seemingly ageless actress turns 54 on Thursday — so this could be a pre-bday celebration.

While Dwyane played a majority of his fantastic NBA career in Miami, he and Gabrielle reportedly are living in Los Angeles these days … and L.A. is where Gabrielle recently made a splash — when she reunited with her “10 Things I Hate About You” co-stars during Julia Stiles‘ tribute to Heath Ledger on “Dancing with the Stars.”

The cast reunion took fans by surprise … and, just like Gabrielle, every one of the stars is aging like fine wine — emphasis on fine!
