Megan Fox and Brian Austin Green step out after baby news

Megan Fox and husband Brian Austin Green stepped out for lunch in Los Angeles on Tuesday (12Apr16) amid the actress' baby news.

The pair has reportedly put their divorce on hold following the surprise baby news, after sources confirmed the couple are working on their marriage.

Megan, 29, showed off her baby bump in a boho style maxi dress while her estranged spouse Austin Green looked laid back in a grey tee and matching jeans. The Teenage Mutant Ninja Turtles actress and former Beverly Hills 90210 star showed little affection, but appeared chatty as they walked alongside each other.

Multiple sources have confirmed to E! News that Brian is the father, and divorce proceedings are now "on hold for a while".

"This pregnancy was not planned, but when they found out they were extremely happy," an insider tells E! News.

Due to Megan's pregnancy they are now "continuing to work on their marriage and are living together again", another source close to the couple added.

While Megan hasn't addressed the pregnancy directly, on Tuesday (12Apr16), she took to Instagram.com and slyly responded to the gossip by posting a photo collage of herself next to three of her past and present male co-stars - Transformers' Shia LaBeouf, Teenage Mutant Ninja Turtles actor Will Arnett, and Jake Johnson, her onscreen love interest during her recent guest arc on sitcom New Girl.

She kept the caption simple, writing: "#NotTheFather".

Brian and Megan have two sons together, Noah, three, and Bodhi, two. The New Girl star filed for divorce from Brian in August (15), ending an 11-year romance and a five-year marriage. She cited "irreconcilable differences" and requested joint physical and legal custody of their boys.
