While vacationing in Hawaii, Brian Austin Green reportedly proposed to girlfriend Megan Fox, but the celebration didn’t last too long since the ring slid off and got lost in the sand, according to Us Weekly. “I saw her jumping up and down,” a witness says of the oceanside proposal. “Later, I saw a half-dozen staff sifting through the sand.” The couple reportedly picked out the two-carat diamond ring together in Beverly Hills. “Security and maintenance staff spent a couple of hours looking for it,” a source says. “No one found it.”
