Anne-Marie Duff insisted there was no rivalry between herself and her Nowhere Boy co-star when they were both nominated in the same category at the British Independent Film Awards.

The former Shameless star beat Kristin Scott Thomas to the title of Best Supporting Actress for her role in the film about John Lennon's early life, but insisted she had her co-star's "genuine" support.

Anne-Marie said: "Kristin and I get on so well and she sent me an e-mail to wish me luck for tonight - genuinely... So I think she'll be delighted to know it went our way, and I think that's the point isn't it?"

The heavy glass award broke in her hands on stage as she made her acceptance speech.

She laughed: "I didn't break it - it just fell apart, but I actually like things that are a bit messed up so that's quite good."

The 39-year-old actress revealed she didn't know where she planned to keep it, adding: "I'm just going to take it home and stare at it for a while and then put it away."

Katie Jarvis, the 18-year-old star of Andrea Arnold's Fish Tank, won Most Promising Newcomer. She was discovered by the director arguing at a station with her boyfriend and asked to be in the film, despite never having acted before.

Katie said: "I'm in shock. If Andrea hadn't picked me for the film I'd probably still be in college doing beauty therapy but this is amazing."

Jarvis revealed she plans to continue acting but is yet to choose a new project.
