Heidi Klum Bikini Pictures in Porto Cervo, Italy

Heidi Klum was in a sexy black bikini in Porto Cervo, Italy, this afternoon after hitting the beach in a pink two-piece earlier in the day. She's been vacationing with her family including kids Leni, Lou, Henry, and Johan all month, and their latest stop is on the island of Sardinia. Heidi's mom, Erna, and dad, Günther, are also along for the trip, and they joined Heidi, who kicked back with a beer, for a relaxing boat ride. The outing on the water was just the latest in a long string of adventures for the busy mom. She and Seal have also been spotted enjoying time on a yacht, shopping, and showing PDA during their extended European stay.
