Emma Watson steps out with Razorlight frontman

Harry Potter star Emma Watson raised eyebrows when she stepped out with Razorlight frontman Johnny Borrell at a London fashion party earlier this week. And the pair got on so well, they attended two more events together.

Emma's lawyer parents aren't going to be happy about their 17-year-old daughter pairing up with the hell-raising rocker, who's almost 10 years her senior - but they needn't worry - the pair parted company by the early hours of yesterday, by which time Johhny - famous for the album 'Up All Night', was seen stumbling solo around the Dorchester Hotel.

The actress and the rock star began the evening at the Vanity Fair and Burberry Portraits party at the National Gallery.

A fellow guest said: "Emma had gone over to speak to Pixie Geldof, who was chatting to Johnny at the time – and Emma and Johnny immediately hit it off.

"It was clear they had loads to talk about – even if they don't look like they have much in common."

The pair shared a taxi to another fashion party, thrown by designers PPQ at the Dolce nightclub. From there, they are believed to have gone on to a private event at London's Dorchester.

Emma and Johnny turned out at the Vanity Fair party along with a host of stars, including Lily Allen, Pixie Geldof, Twiggy, Bryan Ferry and Will Young to celebrate the launch of an exhibition of photographic portraits which have appeared in the US magazine Vanity Fair over the course of nearly 100 years.

Pixie Geldof, 17, the daughter of Bob Geldof, mixed with singer and chat show host Lily Allen, 22, and daughter of actor and hardman Keith Allen, who in turn chatted with Kate Sumner, 25, the daughter of Sting.

The party was thrown by Graydon Carter, Vanity Fair's flamboyant editor, who flew over from the US to host the event.
