HOT Heidi Klum doesn’t get a lot of time off to relax. On top of chasing after her four ankle-biters, the gorgeous MILF is also the hardworking host of hit US telly shows Project Runway and America’s Got Talent. So when the 44-year-old German superstar does get a little DOWN TIME, she really GETS DOWN. Klum recently unleashed her RUNWAY FUNWAYS in Mexico while kicking back on a holiday in Cabo San Lucas, frolicking in the pool with her German muso boyfriend Tom Kaulitz. It’s a cultural thing, we assume – these Euro-types don’t have a problem dropping top and showing the grateful paparazzi their pale-but-perfect bods. If you’ve ever had the pleasure of watching German TV, you’ll know it’s CHOCKERS with BARE FLESH. Naturally, Heidi has those same HARDCORE Teutonic values, telling journos, “I’m a German girl and we like to go topless. I don’t love the tan lines!” Hopefully, on her next holiday, Heidi will avoid the tan lines DOWNSTAIRS, too!
