NEW YORK: Whip it star Drew Barrymore was left covered in bruises after a training session for the roller derby movie went wrong.

The Hollywood actress who makes her directorial debut and stars in the movie about a roller derby team was left black and blue when a training session with Detroit Derby Girls star Racer McChasHer went wrong.

Drew explained, “We were wrestling and rolling around on the track, one of our skates and both our body weights were on my thigh. I had a bruise that was a foot long and a foot wide. My entire leg was covered.”

However, the 34-year-old star has joked she didn’t mind rolling around with the professional skater. She added, “I don’t think there’s anything hotter or more fun to do than a girl fight!”
