It's 'take your bikini top off day while on vacation' apparently.  Cindy Crawford and family are vacationing in St. Tropez and Cindy definitely rocked her 2-piece.  And now, well, she's rocking her bottoms - the 42-year-old mom of two showed off her assets while sunbathing.  As well, sexy Heidi Klum and her family are enjoying the rays and she didn't want pesky tan lines either.  Only way to solve that problem is take off your top!

More photos after the jump!

Cindy and hubby Rande Gerber are celebrating the 20th Anniversary of Cindy's first Playboy appearance.  Twenty years later, mama still looks good!

Heidi, hubby Seal and their kiddies were enjoying the sun in Italy.  And the paparazzi were enjoying the view.
