From Starpulse: "Miley Cyrus and fiancé Liam Hemsworth dodged the cold weather last week to celebrate Liam's birthday in Costa Rica. A pair of fansites snapped photos of the two enjoying some time with friends at a secluded river. ... They look a little cold, but at least they seem to be having fun."
