Megan Fox has given birth to a baby boy.

The 27-year-old actress and her husband Brian Austin Green, 40 - who already two-year-old son Noah - welcomed their second son into the world on Thursday (13.02.14), according to

The couple - who married in 2010 - are yet to reveal the name of their newborn and details of the birth.

Brian - also has 11-year-old son Kassius with his ex-partner Vanessa Marcil - was said to be over the moon when he found out Megan was expecting another boy.

The former 'Beverly Hills 90210' star recently admitted he had ''no idea'' how he and his wife would juggle two babies at the same time, but were just hoping for a healthy newborn.

He said previously: ''I have to say, we honestly have no idea and we discuss it daily and think, 'How are we going to do this?' I think we'll just see when it happens. People do it all the time.''

He added: ''I'm [just] hoping for a healthy baby.''

Megan also said last year being a mother to Noah has helped her take her mind off the pregnancy.

She said: ''I don't have time to think about [what's different this time], I have a one-year-old running around. And then when you're working like 16 hours a day, there's no time for you at all.''
