On Saturday night she was out having a quiet burger with fiancé Ashton Kutcher.
On Sunday Mila Kunis got a very noisy reception as she accepted the award for best villain at the MTV Movie Awards in Nokia Theatre at the L.A. Live entertainment district in Los Angeles.
The 30-year-old has yet to confirm whether she and Ashton are expecting their first child.

Is she protecting a baby bump? Mila Kunis put her hand on her abdomen as she walked up to the stage to receive her best villain honour at the MTV film awards in Los Angeles on Sunday
But she put her hand on her abdomen at one point during the awards ceremony as if she was trying to protect something and she appeared to be a little less slender than usual in side shots.
However, her flirty little black dress did a good job of hiding any possible growing baby bump.
The Ted star allowed her shiney brunette tresses to fall around her shoulders and frame her perfectly made-up face as she picked up the honour for her performance as Theodora, Wicked Witch of the West, in the film Oz: The Great And Powerful.
Something's up: The actress, who got engaged to Ashton Kutcher in January, didn't look her usual slender self as she accepted the award for her role as Theodora, Wicked Witch of the West in Oz: The Great And Powerful
The awards caps an exciting few months for the stunning actress, who revealed her engagement to Ashton, 36, her former That '70s Show co-star, in February after almost two years together.
With the pregnancy rumours gaining momentum, it's not known if the pair will put the wedding on hold until after their child arrives or if they will tie the knot before the birth.
Last week, Mila appeared on an episode on Ashton's CBS sitcom, Two And A Half Men, where she played his character Walden Schmidt's love interest.
