Brian Austin Green let the cat out of the bag.  Responding to a fan on Twitter, the actor described himself himself as being "engaged."  He didn't mention his lady's name, but the only one seen on his arm in many months has been Transformers hottie Megan Fox.

Brian's no stranger to the engagement game.  He and Megan were reportedly engaged in late 2008 but Megan ended the entire relationship in February, 2009. The pair reunited last summer and have been inseparable ever since.

Brian Austin Green has listed his Hollywood Hills mini-mansion for sale, and a source told RadarOnline.com it may be because he and girlfriend Megan Fox are looking to buy a new place where they’ll live together.

Best-known for his years on Beverly Hills 90210, Green has owned his 1920s English Tudor home since 2001.  It has 4 bedrooms and 3.5 baths in 3374 sq. ft.  There’s a pool, of course, and the property is walled and gated.  The asking price is $2,395,000.

Any new home Green and Fox may buy together will have to be kid-friendly.  Brian has shared custody of his seven-year-old son Kassius with ex-girlfriend Vanessa Marcil.
