Megan Fox is reportedly expecting her first child with husband Brian Austin Green.

A source has confirmed to E! News that the couple are indeed preparing to expand their brood.

The actress expressed her desire to become a mother in Cosmopolitan magazine's April issue.

"I want at least two, probably three kids," she shared. "I've always been maternal."

Megan and Brian are thought to be keeping the pregnancy private for now.

"They just found out and are incredibly excited," a source told Star magazine previously. "It's still early, so they are only telling close friends and family members."

Brian has 10-year-old son Kassius with his former partner Vanessa Marcil.

Megan herself has no children from previous relationships.

The Friends with Kids actress and Brian wed in a private ceremony in Hawaii in 2010. The pair met while filming TV show Hope and Faith in 2004 and have been an item since.

Megan's representatives have not yet confirmed the pregnancy.
