HER own cameo may have been cut from the film, but Cecelia Ahern was centre stage at the glitzy London premiere of Love Rosie.

The film, based on Cecelia's 2004 novel Where Rainbows End, stars Lily Collins, Sam Claflin and Suki Waterhouse.

Cecelia looked stunning as she walked the red carpet in Leicester Square.

She was joined at the premiere by husband David Keoghan, her dad Bertie and her mum Miriam.

Lily Collins, the daughter of musician Phil Collins, plays Rosie, whose whole life seems ahead of her until she gets pregnant in a one-night stand and becomes a single working mum, while best friend Alex (Claflin) goes off to university in America.

Despite circumstances keeping them apart, Alex and Rosie can't ignore their feelings for one another.

Although it was shot in Ireland, the film is set in England.

Speaking ahead of last night's premiere, Cecelia said her cameo appearance in Love Rosie had been axed.

"I was an extra for a day but apparently they have cut my scene," she said. "I'm trying not to take it personally!"

She told the RTE Guide that she "can't wait" for the film to come out later this month.
