Helena Bonham Carter loved getting paid by her boyfriend to lust after Johnny Deep in the trio's new movie. The British actress - who stars as Mrs. Lovett in 'Sweeney Todd: The Demon Barber of Fleet Street' directed by her long-term love Tim Burton - had no qualms about falling in love with Tim's best friend, who plays the murderous barber, on screen.

When asked if she found it awkward lusting after Johnny in front of Tim, she told BANG Showbiz: "Weirdly not, maybe it should have been, but you know I was pretending. It is odd, I was being paid by my boyfriend to fall in love with his best friend. It was a strange situation."

Helena - who gave birth to her second child with Tim last month - also revealed she tried extra hard in her audition because she didn't want to feel like she only got the part because she slept with the director.

She added: "I would safely say it made it much harder for me to get the part because the director was my boyfriend. He told me you look right for it, and potentially you are perfect for the role, but we have no idea if you can sing. I said well I will go away and try to learn, but I had to be righter than right. For my sake, I didn't want to feel like I got the part just because I slept with him. But at the end of the day Stephen Sondheim, who wrote the original musical, had the final say and I definitely didn't sleep with him!"
