It came as a shock that Megan Fox is pregnant with her third child even though she's getting divorced- in fact, it was a shock for her ex as well.

On Saturday, People got some scoop from Brian Austin Green who's in the process of ending his marriage with the actress while also planning their third child together. He pointed out that he wasn't exactly expecting this to happen.

"You know, nothing is planned," Green said at the Toyota Grand Prix of Long Beach Celebrity Race. "None of them are ever planned. You kind of just go with it."

Due to the actor's age and having his other children, Noah, 3, and Bodhi, 2, he's just doing what he can to get by.

"At my age, to be having three babies, is crazy," he said. "I'll be 43 this year."

Green reportedly raced at the event where his future ex-wife arrived to show her support.

"Megan looked amazing," a source said. "She was in a great mood too. She seemed to enjoy the event. She watched the race from the sidelines."

Green dished on picking up racing as a hobby and the thrill of doing something a little risky.

"It used to be just the rush of doing it," he said. "You know, it's a different feeling, a different rush than you are used to, and now that I've got all the kids that I have it's like, 'Yeah, this is fun.'"

According to a post from Hollywood Life, Fox and Green may have certain issues, but they still seem to care deeply about each other and raising their family.

"They spend every day together raising their kids, and despite their issues in the past, they still have a strong bond and attraction," a source said. "They may not always get along well, but their connection is real."
