One Direction band singer Harry Styles and the Rolling Stone legend Mick Jagger have found new unlikely friendship.

Styles was invited to join Jagger at a party for the band during their recent tour and the former is said to have "taken a shine" to Styles, reports femalefirst.co.uk.

Styles has in the past already made it clear he's a big fan of Jagger's work, and following the event where they met, Jagger described him and his fellow bandmates as "lovely young lads."

"Harry made it clear he was a huge fan of Mick but never expected he'd take any notice. But people kept telling Mick how much Harry looked like a younger version of him so he started to investigate One Direction," said a source.

"Mick's not a massive fan of their music because he's a rocker to the core, but he thinks they're lovely young lads and took a shine to Harry. He invited him to a special party during the Stones' tour and they instantly hit it off," the source added.

Thrilled with his new friendship, Styles now regularly catches up on the phone with Jagger.
