Miley Cyrus wore a bikini Thursday to hit the beach with her boyfriend, Liam Hemsworth, in Malibu. Earlier this Summer, Miley and Liam went jet skiing in another two-piece during a trip to Michigan. During their latest loved-up afternoon, the couple snapped photos, dipped their toes in the chilly Pacific waters, and lounged casually on the sand. Miley's special outing with Liam comes just after she took a trip to Haiti. She visited the struggling country last weekend on behalf of the Starkey Hearing Foundation, and during her stay in Port au Prince, she aided doctors and volunteers with fitting Haitians with hearing aids. Back in the states, Miley's family got the exciting news that her brother Trace Cyrus is engaged to Brenda Song. He shared their news by tweeting, "I am very excited to say, last week I asked my girlfriend Brenda Song to marry me and she said yes! We are both very excited to be engaged!"
