Last weekend, Megan Fox was engaged to Brian Austin Green ... for the second time "We're just even more committed to each other than we always have been," Fox told PEOPLE at the 'Jonah Hex' premiere. "I'm more in love with him now than I was in the beginning."

Green, 36, proposed to the 24-year-old 'Transformers' star June 1. The two got together in 2004, became engaged in 2007, and called the engagement off in 2009. "It's really not a re-engagement," Fox said. "It's just the same engagement and for some reason now it's a news story."

Fox recently told reporters, "Oddly, you wouldn't think it, but I'm very domestic. That keeps me sane." 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."Before Fox and Green nixed.

Their first engagement, Green spoke of his ideal wedding, telling PEOPLE, "[The ceremony will be] small ... Originally we were talking elopement and now we might have a few people there." Recently, Fox either quit or was fired from 'Transformers 3,' depending whom you ask, and was possibly replaced by a Victoria's Secret model.
