Judging by Borrell's perfomance last night, Watson could have her hands full with the hell-raising rock star.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.Borrell's ex-girlfriend Camilla Fayed was also at the event.Otis Ferry, 25, Master of Foxhounds and son of pop singer Bryan Ferry, was also in attendance.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 couple shared a cab 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 the Dorchester.But actress Emma Watson appeared to fall under the spell of hell-raising rock singer Johnny Borrell when she met him at a London fashion party.The 17-year-old schoolgirl, in flesh-coloured halter neck dress and killer heels, was soon chatting with the star of the group Razorlight.
He even brought along his father who at 62 was - how should one put this - one of the older faces in the crowd.
But the good news for them is that Emma and 27-year-old Borrell had parted company by the early hours of yesterday, by which time he 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.
But there was no sign of Miss Watson by 2.30am, by which time Borrell and another female friend were being shown the door for their over-exuberant behaviour.
As Harry Potter's sidekick Hermione Granger, she has little problem defending herself from the most wily of wizards.And they got on so well that they went on together to two further events.
