Heidi Klum has posed in a stunning pink bikini, while on vacation with her husband, Tokio Hotel rocker Tom Kaulitz, 31. The 48-year-old America’s Got Talent judge took to Instagram on August 4 to share a snap of herself soaking up the sunshine on a boat. She opted for a two piece swimsuit, featuring a bubblegum pink top and matching, high-cut bottoms, which she paired with gold body chains and dark shades.
