Jay-Z wants yoga lessons from Chris Martin.

The '99 Problems' rapper has been supporting Chris' band Coldplay on tour and admits he is envious of the singer's on stage flexibility and wants to be able to mimic his movements.

The hip-hop star - who is good friends with Chris and his wife Gwyneth Paltrow - said: "I try and work out four times a week - cardio, weights, push ups, pull ups - but I haven't for a month because of vacation and touring.

"Chris hasn't tried to get me to do yoga yet but I am close to doing it. I'm envious of what he can do on stage. Watching him is amazing, he can really move. I want to be able to move like that, get my leg behind my ear, things like that."

The rapper - who is married to Beyonce Knowles - enjoys life on the road but admits he misses his home comforts.

He added: "I miss my bed, the comfort of your own bed, there's nothing like it. I only trust my own sheets. I don't take my own with me though."
