After calling off their previous engagement in February of 2009, it's been confirmed Megan Fox, 24, and Brian Austin Green, 36, are engaged again.  On June 1st, Brian proposed to Megan at the beach by the Four Seasons Hulalai Hotel in Hawaii.   Apparently, the 2-cart diamond ring was lost during the proposal, according to one witness, "later, I saw a half dozen staff sifting through the sand."  The two have been dating on and off since 2004.
