exposay - Leonardo DiCaprio is having singing lessons to sound like Frank Sinatra. The "Titanic" actor is keen to portray the legendary singer in a new biopic but needs to prove to director Martin Scorsese he has the vocal talent to carry it off.
A source told Britain's The Sun newspaper: "Leonardo has hired a top vocal coach to get him sounding like Sinatra. He is a massive fan of the singer and has always wanted to play him. He would be upset to miss out on the leading role because his singing wasn't up to scratch.
"He is now in intensive vocal coaching lessons to replicate Sinatra's distinctive style."
However, Leonardo faces competition from stars including George Clooney, Justin Timberlake, Harry Connick Jr. and Jamie Foxx.
It was recently claimed Jamie - who played jazz musician Ray Charles in "Ray" - is being lined up to portray the Rat Pack singer after film bosses saw similarities between the two stars' backgrounds.
