Dakota Fanning would be Beyonce Knowles "in two seconds" given the chance.

The actress has risen to international fame thanks to roles in high-profile films including The Twilight Saga series, Man on Fire and War of the Worlds.

Dakota has Hollywood at her feet, but still admires the lives of other worldwide superstars.

"I love who I am and I love my life but if I could be someone else I'd be Beyonce in two seconds," she smiled in an interview with British newspaper The Telegraph.

Dakota stars in Now Is Good, an adaptation of Jenny Downham's novel Before I Die. The story follows a girl dying of leukaemia who has a bucket list.

The 18-year-old star says children are certainly on her list of life ambitions - despite not talking about her relationship status.

"I want to have a million babies!" she giggled. "Not that I'm getting started now! I have plenty of time."

Dakota tries to remain independent - and is currently studying at New York University. The star misses her tight-knit family at times though.

"I was saying to my mom the other day, it's so weird not to have anyone around to run things by. Like, I'm going to eat dinner now! Or I need to go do this" she mused. "You're all by yourself. It's crazy. But it's really good for me, I think.

"My mom and I have been pretty much together my whole life, because when I was working before I was 18 she was always with me."
