"Transformers" beauty Megan Fox could be engaged to boyfriend Brian Austin Green once again. The speculation suggesting the two might have been betrothed once more has surfaced after Fox's boyfriend, Green, wrote that he is "engaged and has a son from previous relationship" in his Twitter account in response to a question asked by a fan on whether he is married and have kids.

On his tweet, the 36-year-old actor didn't give any indication that he is specifically engaged to the 23-year-old actress. Still, the former "Terminator: The Sarah Connor Chronicles" star tweeted earlier that he was with Fox in New Mexico while she filmed her new movie "Passion Play". So far, the duo haven't released official statement regarding the engagement rumor and Green's Twitter page has apparently been deleted.

Megan Fox was engaged to Brian Austin Green in late 2008, but the "Jennifer's Body" actress later called off the engagement when they split in February 2009. She and Green reunited in summer 2009. The speculation about the two taking the relationship to the next level might be true considering the fact that just last week, Fox purchased a $2.9 million house in Los Feliz, Los Angeles, California, which according to reports, she bought for their love nest.
