Megan Fox’s on-off boyfriend Brian Austin Green has announced on Twitter that he is engaged.

Asked if he was married the actor wrote: “Engaged and have a son from my previous relationship.”

And it looks likely that the gorgeous actress is the lady with the ring on her finger.

Green recently said that he was in New Mexico with Fox while she filmed a new movie.

The stars were engaged before splitting in early 2009. Now it seems that one of them has popped the question again.
