Helena Bonham Carter thinks Johnny Depp's singing voice is "incredibly sexy"

Actress Helena Bonham Carter thinks her Sweeney Todd co-star Johnny Depp has an "incredibly sexy" singing voice.

Helena - who stars alongside Depp in the new Tim Burton film 'Sweeney Todd: The Demon Barber Of Fleet Street', discovered a whole new side to the actor when she first heard his "naked" vocal talents.

She said: "Johnny's singing voice is incredibly sexy. He really sings from the gut and it's a very emotional role. His singing is very naked and very touching."

Helena also said it was hard working under the instruction of her long-term partner, director Tim Burton.

She added to Britain's Independent newspaper: "I've learned not to talk so much and basically just obey him because he's the chief at work. It can be difficult living and working together.

"It depends on the day. Sometimes we revert to a couple and our relationship at home on set, which isn't help
