Megan Fox "loves" being pregnant.

She explained: "I love being pregnant, which is, a lot of women don't feel that way, it is really uncomfortable... by the way. It is painful at parts.

"I feel the overall process is an amazing one. I feel so productive creating a human person that I'm so excited to meet because I know that I have such a spiritual connection to them, so I can't wait to meet this new member of my family."

The new bundle of joy, who is believed to be due in autumn, will join the estranged couple's other two children Noah, three, and Bodhi, two, and they can't wait to meet their little sibling.

Speaking to 'Extra', Megan said of her children: "The older one [Noah] is very excited [about having a little sibling].

"The older one is excited. Bodhi is too young. He gets it, but he's still in that sort of oblivious phase, like, 'What are we playing right now?' He's not thinking about the future. But Noah's really excited. He's actually really maternal, and he can't wait to feed and hold and pet the baby. He's practicing a lot with baby dolls. He's doing a good job."

Meanwhile, the pair's pregnancy news shocked fans earlier this year as it came just after they announced they'd split.

The brunette beauty filed for divorce from Brian, 42, last August but they are now closer than ever and are currently getting the nursery ready in their Bel Air home for the baby.

A source said recently: "This pregnancy was not planned, but when they found out they were extremely happy.

"Megan and Brian love being parents. They are working really hard to be together and one unit--not only for their children, but also for each other.

"They are looking forward for the arrival of their new baby. Brian has been a great partner and father."
