Megan Fox and Brian Austin Green reportedly have a bun in the oven -- at least according to a tabloid report.

Star Magazine has broken the news that Fox, who married the former 90210 star in 2010, is in the early stages of pregnancy.

They just found out and are incredibly excited, an unnamed friend of the couple told star.

It's still early, so they are only telling close friends and family members.

Green has a ten-year-old son, Kassius Lijah, with his ex-girlfriend Vanessa Marcil.

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

Kassius was the only witness at Fox and Green's private 2010 wedding, according to the New York Post.

Green praised her step-parenting skills earlier this month.

She's an amazing stepmom, Green told People magazine. [My son] loves her. They have a great relationship. She's always had a special bond with him. They love each other to death.

Fox has made no secret of her desire to have children of her own.

I've always really loved kids, Fox told People. I was a good babysitter. I've always loved babies. I relate to kids pretty well.

Asked if she intended to have a baby, Fox said, Of course. It will happen when it's meant to happen.

The Transformers star is apparently ready to make someone else the center of her attention after spending years in the spotlight.

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