Mila Kunis made no attempt to dispel pregnancy rumours at the MTV Movie Awards on Sunday (13Apr14), when she rested her hand on her belly during her acceptance speech.

The actress has kept quiet about reports suggesting she is expecting her first child with Ashton Kutcher, but she gave her biggest hint yet at the glitzy bash in Los Angeles.

Kunis sported a fuller figure when she took to the stage to pick up the Best Villain prize for her turn as the Wicked Witch of the West in Oz The Great and Powerful, and she also placed her hand protectively on her belly as she thanked her fans for the award.

She said, "Listen you guys. You just made my 12-year-old self's dream come true. This is by the far the coolest award and I just realised I was the only woman nominated, and I won. So thank you guys."

Reports suggest Kunis is also engaged to marry Kutcher, who she has been dating since 2012.
