Megan Fox shows off baby bump

There's only so long you can keep pregnancy a secret. It looks like in the case of Megan Fox, the truth is becoming obvious.

Photos have emerged of the "Transformers" star sporting what appears to be a baby bump while out and about in Los Angeles. The normally svelte 26-year-old is seen in pictures acquired by E! News resting her hands on an emerging belly.

While Fox and husband Brian Austin Green haven't formally announced whether they're expecting, a source tells the publication that it's true. The child will be Green's second and Fox's first.

Fox has expressed her interest in having children. In an April interview with Cosmopolitan, she says, "I want at least two, probably three kids...I've always been maternal."

It appears that one is already on the way.
