Mila Kunis was a vision in white when she filmed a wedding scene with onscreen beau Mark Wahlberg Thursday. Wearing a strapless mermaid gown and a short veil, the 27-year-old actress looked every inch the blushing bride. Wahlberg, meanwhile, looked dapper in a black suit and bowtie.

The costars have been filming Ted for the past few months in Boston (Wahlberg's hometown).

Directed by Family Guy creator Seth MacFarlane, the rom-com tells the story of a man and his teddy bear, which comes to life as the result of a childhood wish. It costars Giovanni Ribisi, Community's Joel McHale and 90210's Jessica Stroup.
