Catherine Zeta-Jones was so overawed by her 2003 Oscar win she had to re-watch the show six months after her triumph just to make sure she wasn't dreaming.

The actress was heavily pregnant with baby CERYS when she picked up the Best Supporting Actress for her role in Chicago and admits that, to this day, the whole event remains one big blur.

She says, "It wasn't until six months later that I was sitting at my computer and I looked up at the Oscar on the shelf and thought, 'Oh my God!'

"I had to re-watch the telecast, because I couldn't even remember what I'd said. I just remember staring at my swelling ankles and thinking, 'I wish I could knock back a bottle of champagne.'"
