Watson, who played Hermione Granger in the movie, went to the club after the final premiere for "Deathly Hallows: Part 2", which is the last of the "Harry Potter" films, reports thesun. "She was really enjoying herself. There were a few scantily-clad girls around but Emma didn't bat an eyelid. There are a few poles in the club but she didn't have a go. After such a big night, it's no wonder she wanted to let her hair down," said a source. She danced the night away with friends. "She had a smile on her face the whole time before calling it a night around 2 a.m.," added the source. The actress was just 11 when she starred in " Harry Potter and the Philosopher's Stone" and was 12 when she featured in the "Chamber of Secrets".
