It's not even been a month to the end of his marriage with singer Katy Perry, but British comedian Russell Brand is reportedly back to his womanising ways.

The 36-year-old, who filed for divorce from Perry Dec 30 last year, is seeing more girls than one, reports contactmusic.com.

"She (Katy Perry) discovered through her friends. One of the women told a friend of hers and it got back to Katy. He's (Russell Brand) spoken terribly about Katy to them. Russell told (one girl) he wanted her to move in with him after the divorce is final," said a source.

Before he started his relationship with Perry, Brand, who married the pop star in India in October 2010, was known for being romantically involved with Kate Moss, Australian actress Teresa Palmer and Holly Madison.
