The Harry Potter actress was recommended lessons by a fellow cast member on her upcoming movie The Bling Ring, reports The Sun.
"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," a source claimed.
Watson also apparently feels the acrobatic art is "liberating".
"She's amazed with the results because it has toned up her body so well," the insider added. "She never thought she would enjoy it, but she finds it quite liberating."
Watson's new film The Bling Ring is directed by Lost in Translation's Sofia Coppola and is expected to be released in 2013.
It is based on the true story of the Hollywood Hills 'Burglar Bunch' responsible for stealing more than $3 million (£1.9 million) in goods from celebrities such as Lindsay Lohan and Paris Hilton, the latter of whom is making a cameo in the movie.
