Transformers star Megan Fox and husband Brian Austin Green have reportedly welcomed their second child - a son.

According to TooFab who first reported the news, the couple who are parents to 15-month-old son Noah, have not released the baby's name or any other details.

Previously, 27-year-old Fox had talked about her "rough" second pregnancy.

"I've had rough first trimesters," she told ABC News. "But once you get into the second, it's fine after that."

Fox and Green tied the knot in a private ceremony in Hawaii in June, 2010 after several years of dating. They originally got engaged in 2006, but called it off in 2009, only to reunite in 2010 and walk down the aisle.

Green already has a 11-year-old son Kassius with ex-girlfriend Vanessa Marcil.

Fox has previously voiced her desire to have more children and give Noah a sibling.

"All I wanted to do my whole, whole life was have a baby and, now, I've finally done it," she said in an interview with Marie Claire.

"I just want to give Noah as much of myself as I can. And I want to have more kids. That is where my heart is."

In an earlier interview with Cosmopolitan, Fox opened up about her desire to be a mother.

"I want at least two, probably three [kids], I've always been maternal," Fox was quoted as saying.

Fox will be next seen in the film Teenage Mutant Ninja Turtles scheduled for release in June 2014.
