Megan Fox and Brian Austin Green have welcomed a baby.

The secret-keeping couple withheld the news that she delivered a baby boy sometime in late September. The Hollywood pair has yet to officially announce the birth with details of the baby's name and weight but E! was the first to break the story and confirm it.

Fox and Green stayed entirely quiet about their impending child even throughout her pregnancy. A source revealed the news to E! back in April. When pictures emerged in June that featured a very pregnant Fox in Hawaii with her husband, the couple still chose to remain mum about the subject.

There was no confirmation that the 26-year-old actress was with child until a photo was released that showed she was visibly pregnant. The photo was published in People in late June. If the picture was anything to go by, the actress was at least three months along. In the photo, Green is standing behind Fox and cradling and caressing her baby bump, which is visible in her bikini top and maxi beach skirt

Once the baby bump became apparent, the happy duo allowed paparazzi to take snaps of them later in August.

Fox told Cosmopolitan in the magazine's April issue that she's "always been maternal" and that she wants "at least two, probably three kids."

The "Friends With Kids" actress also told E! Online that "it's going to happen when it's going to happen, but it's not something that I've planned against or for. I'm just leaving it out there for the universe." 

Fox continued: "I just feel like kids are so much more important than any movie about robots or...you know...They're just so much more important than that. I'm not worried."

The pair tied the knot in June 2010 in Hawaii, their rumored favorite vacation spot. Green has a 10-year-old son, Kassius, to whom Fox is a stepmother to.
