Heidi Klum and Seal lounged on a floating raft near the Italian island of Sardinia today. The couple's latest beach afternoon was filled with PDA and more family fun that included their kids, Johan, Henry, Leni, and Lou. We've seen Heidi Klum in a bikini often during the Klum-Samuels' extended European vacation, and Seal's been in his own sexy suits. Heidi's parents, Günther and Erna, are also along for the getaway, which kicked off earlier this month in Spain. The whole crew seems to be enjoying their stay in Porto Cervo for now, though we'll have to wait and see if their travels take them to another sunny locale.
