Emma Watson was spotted partying at a strip club in New York as she celebrated after the Harry Potter and the Deathly Hallows: Part 2 premiere.
However, Watson did not have a go dancing around the poles herself, a witness said.
A source told The Sun: "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."

Emma Watson won praise for her outfit at the Harry Potter and the Deathly Hallows: Part 2 New York City premiere on Monday night.
The actress wore a gold and bronze Bottega Veneta dress with a canvas corset and satin skirt. She added a bit of rock and roll with dark, glittering eye make-up and wore her hair scraped back.
It appears that Watson is more enamoured with her US fans than those back home.
Speaking on Late Show with David Letterman, she said: "British audience members will come out and say, 'Well, that was very good’. The American way is 'That was awesome!'"
"As much as I love being in the UK, that's the kind of response you want to get to your movie."
