Mexican actor Diego Boneta became firm friends with Rock Of Ages co-star Tom Cruise as they prepared to play rockers for the much-anticipated movie musical - they shared the same guitar teacher.
When Cruise discovered he and his castmate were both studying with the same expert, he proposed they jam together on set.
Boneta says, "Tom noticed we were sharing the same teacher and he approached me... I was so honoured!"
And the young star still can't believe he befriended Cruise on the set of his first movie: "He was definitely somebody I looked up to growing up. I told him it was my first movie and he took an interest in me. He gave me a lot of powerful advice during the filming. I could say he was mentoring me.
"Tom is by far the most dedicated and professional individual I’ve ever worked with."
Cruise makes his movie musical debut as rock star Stacee Jaxx in the film, while leading man Boneta plays wannabe Drew Boley.
