Russell Brand stops threesome sex for Katy Perry

London (ANI): British stand-up comedian Russell Brand, who is renowned for being a womanizer, has announced that he will no longer indulge in threesome sex.

The funny man told a crowd of 5,000 people present at his Royal Albert Hall gig that he has sworn to remain loyal to girlfriend/singer Katy Perry.

"I've taken a pledge. I can't break it now. There will be no more threesomes," the Sun quoted him as saying.

Brand was later snapped with Perry in an aftershow party in Hampstead. The concert was the last of his Scandalous tour shows.
