Megan Fox Opens Up About Giving Birth: "It Hurts So Bad"

Megan Fox could strike any fellow as a Transformer herself.

Only 10 weeks after giving birth to her first baby boy Noah, the sizzling actress seems to have brought her pre-baby sexy back. She flaunted her curves at an appearance alongside husband Brian Austin Green at the March of Dimes Celebration of Babies Luncheon in Beverly Hills on Friday and opened up about the painful delivery.

"I was screaming for an epidural when [Brian Austin Green] was driving me to the hospital because my water broke on its own and I was immediately -- it was level orange alert pain," Megan told Access Hollywood at the "This Is 40" film junket Monday (Dec. 10).

"It... can't be anything because it hurts so bad," Megan said. "It was so intense. And I thought I was gonna be really tough and make it, I was gonna labor to like 8 cm... but the first contraction that I got was horrific!"

The "Transformers" star had kept hush about her little bundle of joy until she broke the news on Facebook. "We have been very lucky to have had a peaceful few weeks at home, but I would like to release this myself before others do. I gave birth to our son Noah Shannon Green on September 27th. He is healthy, happy, and perfect," Megan wrote. "We are humbled to have the opportunity to call ourselves the parents of this beautiful soul and I am forever grateful to God for allowing me to know this kind of boundless, immaculate love."

Now the new MILF says she's elated to have a little one of her own. "It's exhausting, but it's amazing and you can't, until you have kids, you can't imagine how much you could possibly love a human being," she said. "It's really intense and really overwhelming and amazing."

The brunette bombshell stars in "This Is 40" with Paul Rudd and Leslie Mann, which opens on Dec. 21.
