Double take!

When Tina Fey's Liz Lemon married James Marsden's Chris Chross on Thursday's anticipated wedding episode of 30 Rock, there was one very special person on set to see the duo tie the knot: Fey's real-life daughter, Alice Zenobia.

Appearing in a flashback scene where Lemon recalled her first wedding experience — as a flower girl — the 7-year-old daughter of Fey and husband of 11 years Jeff Richmond starred as Lemon's younger self.

For her appearance, Alice donned a blue dress and headpiece and showed off a major attitude, complete with an eye roll.

Prior to walking down the aisle with Chross, Fey's character, a 42-year-old unlucky-in-love TV producer, previously dated commercial pilot Carol Burnett (Matt Damon), juvenile businessman Dennis Duffy (Dean Winters) and hapless-but-hunky Dr. Drew Baird (Jon Hamm).

Costarring Alec Baldwin, Jane Krakowski, Tracy Morgan and Jack McBrayer, 30 Rock will wrap its seven season run with a one-hour series finale on January 31.
