The Transformers beauty stunned fans in April (16) when she arrived at a CinemaCon event in Las Vegas to promote Teenage Mutant Ninja Turtles: Out of the Shadows with a noticeable baby bump.

She has since confirmed her happy news, which emerged eight months after she filed to end her five-year marriage to Brian.

Megan and the former Beverly Hills, 90210 actor, who are also parents to sons, Noah, three, and Bodhi, two, have reportedly moved back in together as they work on their relationship, and actress Brittany Ishibashi is hopeful the baby will help the couple fully reconcile.

"I have a two-year-old. We bonded over kids," she told of how she got to know Megan onset. "And I worked with Brian Austin Green a few years ago on Desperate Housewives. He's such a sweet guy.

"They are both such sweet people - super chill," she continued while attending the New York premiere of the Teenage Mutant Ninja Turtles sequel on Sunday (22May16). "They're very spiritual people, very kind and generous. And she's an amazing mother. She was always talking about her kids and FaceTiming with her kids. And I think Brian's a great dad. They're such cool people."

Brittany admits she has been secretly cheering them on after photos of the reunited pair on a recent vacation in Hawaii hit the Internet. The islands hold a special significance for Megan and Brian.

"I was like, 'Aw, there you go, guys,'" Brittany said. "And the big island on Hawaii is a very special place, very spiritual - that's where they got married, at the Four Seasons on the big island of Hawaii, at Hualalai. And they were back there."

Pregnant Megan, who turned 30 last week (16May16), was a no-show at the Big Apple screening of Teenage Mutant Ninja Turtles: Out of the Shadows after feeling "under the weather", but that didn't stop her other co-stars from showing their support for the actress.

"She's an amazing mum," actor Pete Ploszek, who plays Turtle Leonardo, gushed. "And she's a real Mama Bear, in the sense that she takes care of us (Turtles), being the savvy industry vet. I saw Brian a lot on movie one, he hung out a lot. So we all became close with Brian. He's a super dad, too."

Megan and Brian, who were together for 11 years before their split, have yet to comment on the status of their divorce, but multiple reports suggest legal proceedings have been "put on hold" due to the pregnancy.

"This pregnancy was not planned, but when they found out they were extremely happy," an insider told E! News last month (Apr16).
