Megan Fox Gets Engaged, Loses RingSorry guys -- America's sexiest gaffe-master, actress Megan Fox, is off the market. Brian Austin Green, 36, proposed to the 24-year-old 'Transformers' star June 1, Us Weekly reports. The two got together in 2004, became engaged in 2007, and called the engagement off in 2009.

"Yes, she is engaged," a rep confirmed to PEOPLE.

The proposal was a beachy affair in Hawaii. A thrilled Fox was reportedly hopping up and down and actually lost her engagement ring, a witness tells the magazine. "Later, I saw a half dozen staff sifting through the sand."

The ring was a 2-carat diamond Fox and Green chose together in Beverly Hills. "Security and maintenance staff spent a couple of hours looking for it," another source tells Us Weekly. "No one found it."
