(Cover) - EN Showbiz - Emma Watson reportedly finds pole-dancing "liberating."

The Harry Potter series actress is currently filming director Sofia Coppola's upcoming feature The Bling Ring. The film, which is based on true events, follows a pack of crazed teenagers who stalk celebrities' whereabouts online so that they can rob their homes.

Emma decided to take up pole-dancing after her friends advised her of the health benefits and she is elated with her new cardio routine.

"Like on all film sets, there's often so much time spent doing nothing," an insider explained to British newspaper The Sun. "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. She never thought she would enjoy it but she finds it quite liberating."

The Bling Ring starring Emma, Kirsten Dunst and Leslie Mann will be released in 2013. (C) Cover Media
