Johnny Depp's daughter is obsessed with Justin Bieber.

The Hollywood star has had to start accepting her 11-year-old daughter Lily-Rose is becoming interested in boys and the Canadian pop heartthrob in particular.

Johnny first realised she was a 'Belieber' when he told her he had met the 'Baby' singer.

He revealed: "Unfortunately, Lily Rose is now severely interested in boys. That's horrible for me as her dad. I recently met Justin Bieber at a press conference. When I told her that, she changed her colour several times. Jack is like me when I was eight. Totally obsessed with World War II."

The 47-year-old actor - who also has an eight-year-old son Jack with his long-term partner Vanessa Paradis - can't believe how mature his daughter is for her age and claims she is already showing she shares her mother's talent for music.

The 'Pirates Of The Caribbean' star added: "She is almost 12 and she's incredible mature for her age, almost frightening smart. She writes little poems and I can picture her starting to write her own songs soon. She has the voice of her mother."
