Amy Winehouse stole her dad's spotlight last night -- and looked great doing it.

Amy's father Mitch was supposed to be the headliner at Thursday's launch party for City Burlesque in London -- but his daughter jumped on stage as well and did a surprise performance for the crowd, according to the Daily Mail.

Compared to some of her messier sightings in the past, Winehouse looked put together at the event -- and most importantly, looked like she was really enjoying herself.

This is Amy's second surprise gig this week -- she also appeared at a charity event Wednesday at her favorite bar, The Hawley Arms.
