Age ain't no thang to Heidi Klum! On Monday, she and her hubby Tom Kaulitz took to the waves in St. Barts for a beach day - and Heidi showed OFF that banging bod of hers! At 52 she's looking as hawt as ever, and these topless pics will have your jaw on the floor. Yup, she took off her mint green wrap top on the sandy shores of the Caribbean and freed the nip!
