Megan Fox Pregnant, Who is the Daddy?

Megan Fox is reportedly pregnant with her first baby. Who is the baby daddy? Well it's her husband, Brian Austin Green, of course! The couple--married two years--is said to be incredibly excited about their wonderful news.

According to a report from RadarOnline, no official announcement has yet been made

because it's still very early in the pregnancy. They have told only family members and very close friends. (It's pretty obvious that someone within that group of 'trusted' confidantes spilled the beans, however, if the media has learned the news!)

The Transformers star is already a stepmom to Brian Austin Greene's son, ten-year-old Kassius.

"Megan has become a great stepmom, and Brian knows she'll be wonderful with the baby," a source says.

It seems being a stepmom isn't the only big change Megan Fox has made throughout the past couple of years either.

"She has really grown in the past couple of years. Megan used to only be concerned with her career, but now family comes first," the source adds.

Although this pregnancy was completely unexpected, both Brian Austin Green and Megan Fox are said to be thrilled with their big surprise. It will be interesting to hear both Mom and Dad's take on the impending birth once they officially go public with the big news.
