Ex-Coronation Street star Michelle looked cosy in a knitted poncho from her own Lipsy Love Michelle Keegan collection, available now for £30.
The 28-year-old posed for a picture in Monica's apartment (making us all very jealous!)
She said: "I am buzzing to see everything at FriendsFest, I love Friends. My friends think I am most like Phoebe, I'm not OCD enough to be Monica!"
Comedy Central's FriendsFest is a week-long interative fan experience in Brick Lane, London, featuring a full scale replica of Monica's apartment, a Central Perk-inspired cafe, and propos from the show.
Show star James Michael Tyler - who played Central Perk barista and manager Gunther - launched the event yesterday, and was at last night's star-studded celebrity evening.
He said: "It's amazing to think that Friends is still as popular today, as it was 21 years ago when we first started. Comedy Central's FriendsFest brings together some of the most iconic sets and props from the show and I'm certain fans will love. I feel extremely nostalgic being back in Monica's apartment and Central Perk."
So, we also said Mark Wright was there... and he was! He seemed to avoid the limelight, however, and stay in the background. We spotted him leaving the venue at the end of the night, still sporting that foot cast after breaking a bone in his foot earlier this month.
