Now here’s a yoga couple I wouldn’t expect…Russell Brand invited Charlie Sheen to join his yoga class.

I can see Russell being all zen, but Charlie Sheen?

A source said:

“Russell and Charlie have been spending an increased amount of time together as they’ve been named by [TV network] FX as the stars for their summer schedule so have done a lot of promotional work together.

“Russell has invited Charlie to join him at his yoga classes.

“But Hollywood is a small place and everyone is worried Charlie might lead Russell astray.

“Russell is a strong guy, he won’t just fall off the wagon, but he’s single after his split from Katy Perry and on the look-out for women – and Charlie’s legendary parties are always packed full of beautiful women.”

Maybe yoga will mellow them both out, or maybe they’ll be two wild and crazy guys!

According to the Daily Star newspaper, a source added:

“Russell’s friends are panicking as Charlie keeps calling him, chasing him to meet up.

“Russell is too kind to say no, he thinks Charlie just needs a friend, someone who’ll look out for him. Russell was once in the same situation, off the rails and lonely.

“But Charlie is a notorious bad boy and will definitely be a bad influence on him.”
