Heidi Klum Rocks Yellow Bikini for Beach Day with Husband Tom Kaulitz in St. Barts

Heidi Klum and Tom Kaulitz are soaking up the sun!

The married couple held hands as they went for a walk along the beach after going for a dip in the sea on Sunday afternoon (January 4) on the Caribbean island of Saint Barthélemy, commonly known as St. Barts.

For their beach day, the 52-year-old Project Runway host rocked a yellow bikini while the 36-year-old Tokio Hotel musician went shirtless while wearing pink swim trunks.

Heidi and Tom have been in St. Barths for the past few weeks celebrating the holidays.
