The most famous bottom in the world is back, as Jennifer Lopez soaked up the sun on a boat ride off Capri. The singer celebrated her 40th birthday last week at a surprise party thrown by husband Marc Anthony, also 40, in New York.

But you'd never guess it as her bikini revealed her bellissima bottom yesterday as she holidayed with her family in the Med. Her tummy, though, was impressively flat given it's just 18 months since the birth of twins Max and Emme. Who could blame J.Lo for showing off a little?
