The cast and crew of Seth MacFarlane’s acclaimed adult animated sitcom Family Guy are celebrating the show’s 400th episode with a bash on the Fox Studio Lot in Los Angeles on Saturday, November 13. Mila Kunis, who came aboard to start voicing the role of Meg Griffin for season two, was among the stars on hand to party it up with her colleagues.

The show, which MacFarlane conceived back in 1995 while studying animation at the Rhode Island School of Design (RISD).

Kunis, 39, stepped out for a round of red carpet photos looking stylish in a black dress that was partially covered up with her rustic brown lather jacket. The actress also donned black shoes and had her dark tresses styled long, straight and flowing down past her chest and back with a part on the middle.

Feeling the excitement of the milestone event, the Ukraine native got playful and posed next to an image of her Meg Griffin character that was adorned on the backdrop of the photo area.

After auditioning for the role, Kunis ended up getting a call back to meet with MacFarlane, who then instructed her to speak slower. She would come back yet again to show off her new and improved enunciation, and once she claimed to have gotten it right where they needed to be MacFarlane hired her to play Meg.

MacFarlane, 49, showed off his fashion sense at the 400th episode celebration decked out in a dark blue suit with a black dress shirt and shoes.
