Harry Styles is apparently planning to take up ballet like his idol Mick Jagger.
The One Direction heartthrob became interested in dancing after chatting to the Rolling Stone's trainer and physio Torje Eike, reported The Sun.
He is now planning to follow Mick to the barre in a bid to stay in shape and have a career as long as the rocker has had.
A source said: "Harry wants a career spanning decades like Mick's and to have that he recognises that fitness, health and developing his body is the key.
"He spoke to Torje about Jagger's intense routine of kick-boxing, running, weights and, most importantly, ballet.
"That's the Achilles' heel in Harry's training. He can't dance and neither can any of the 1D boys - their choreographer recognised early on that they shouldn't dance on stage."
The boy band are already working hard on their fitness with personal trainer Mark Jarvis while they are touring. And Mark's boss Ramzy Khachik thinks ballet would be a good addition to their regime.
He said: "Harry sees how supple Mick is, how he manages to stretch his body and do contortions. It's a brilliant art form and will get more grace into his movements - if you're graceful you can get away with minimalistic moves, which is what their choreography is about."
Mick, 69, revealed last month that he manages to keep his figure on point with ballet dancing.
He said: "I train five or six days a week. I alternate between gym work and dancing then I do sprints, things like that. I'm training for stamina."
