Watson takes up pole-dancing

London, May 12 (IANS) "Harry Potter" actress Emma Watson has taken up pole-dancing after it was recommended by a friend and is impressed with how toned it has made her.

"Like on all film sets, there's often so much time spent doing nothing. One of the other actresses on the set has been pole-dancing as a sport for a while and Emma decided to give it a go as well. She's amazed with the results because it has toned up her body so well," a source told thesun.co.uk.

"She never thought she would enjoy it but she finds it quite liberating", said the source.

Last summer, following the New York premiere of "Harry Potter and the Deathly Hallows: Part 2" she partied at a pole-dancing club with pals.
