Russell Brand reveals Harry Styles yoga session

Russell Brand has joked he does yoga with Harry Styles.

The British comedian hit headlines recently following claims he had bonded with Demi Moore over the stretching exercise.

The star apparently also partakes in group yoga and quipped the One Direction heartthrob joins in with special sessions held at Russell's home.

"I am afraid [Harry Styles] is taken, he's one of the people doing yoga in my house right now," he laughed to BBC Radio One about the singer, who celebrates his 19th birthday today.

"Like 100 [people do yoga in my house]... It was alright, it was a bit cramped. [Yoga] will liberate you from the material world in a safe and lovely way. It should be a daily practice. Think of all the things you do every day; drink coffee smoke a cigarette... It will open up your mind to realms and realms of new things."

In aid of British charity Comic Relief, Russell is launching the Give it Up concert, which will feature stars such as Nicole Scherzinger.

The long-haired funny man admires the former Pussycat Doll for her down-to-earth attitude.

"You saw her using an escalator? Oh, that's brilliant. That's classy! She utilised the escalator," he laughed. "A lot of people would say, 'Oh no, I'm scared of that! What if I catch my long, silken boa?' But Nicole, she's up and down that. Me, I'd be like, 'Stop the thing!'"

Russell will host the Give it Up event, which aims to raise money for those struggling with alcohol and drug addiction.

The 37-year-old admits he's nervous and would like a little help from some fellow famous faces.

"There's a lot of pressure. Florence [Welch], she needs to do it. Get up on stage! Or Adele," he said.

"Prince, I love you ever so much. If you're in a room now with Prince get him to come up here. I tried to email him but I haven't had a response."
