Brooke Shields, 52, flaunts bikini bum in tropical vacation pics

Brooke Shields is feeling confident in her skin!

The iconic fashion model, 52, has been enjoying an exotic beachside vacation with her family, as proven by her recent Instagram snaps, including two bikini pics she shared that showed off her healthy physique.

In a March 25 snap, Shields posed in a black-and-white bikini with the gorgeous surf behind her. And speaking of behind, The Blue Lagoon actress also gave fans a peek at the back of her swimsuit (and her bum!) as she enjoyed "paradise."

"Bikini life in paradise," she captioned the pics.

It's not the first time mum-of-two Shields has showed off her fit frame in recent months.

Last June, she celebrated the anniversary of her first Calvin Klein campaign -- 37 years later! -- by posing in a white Calvin Klein Fit Me bra and matching briefs.

You go, Brooke!
