Megan Fox Makes an Honest Man of Brian Austin Green

“Transformers” star Megan Fox and Brian Austin Green wed in a private ceremony at the Four Seasons Resort on the Big Island in Hawaii -- just one week after they were engaged on the island, TMZ reported Monday.

Fox, 24 and former "90210" star Green, 36 -- who began dating in 2004 after meeting on the set of the sitcom “Hope & Faith” -- were married late last week.

Fox was so excited by Green's beachside proposal she lost the two-carat engagement ring, Us Weekly reported.

"Security and maintenance staff spent a couple of hours looking for it," a source told the magazine. "No one found it."

It was the couple's second engagement after ending their previous two-year engagement last year.
