A baddie with a bump! Pregnant Mila Kunis kept her tiny baby belly under wraps in a little black dress at the 2014 MTV Movie Awards on Sunday, April 13, where she picked up the trophy for Best Villain.

The star -- who is expecting her first child with fiance Ashton Kutcher later this year -- looked radiant as she took the stage at Nokia Theatre L.A. Live to accept the tub of golden popcorn for her role as the Wicked Witch of the West in Oz The Great and Powerful. Her LBD helped camouflage her new curves, but there was definitely the hint of a bump underneath. See more pics of Mila here.

"This is, by far, the coolest award," she told the crowd of screaming fans. "And I just realized I was the only woman nominated, and I won! So thank you guys."

The pregnant That '70s Show alum then disappeared backstage, only to reappear a few minutes later to present the Trailblazer Award to her Jupiter Ascending costar Channing Tatum. Praising his ability to do both comedy and drama, the actress, 30, introduced a highlight reel of Tatum's movie clips.

Kunis' bump made its red carpet debut in late March, at the premiere of Jupiter Ascending at Cinemacon in Las Vegas. She's "all about being a mother," a source told Us Weekly, adding that she and Kutcher, 36, are "happy, healthy, and excited to start a family."?
