Harry Potter star Emma Watson is denying she is dating Johnny Borrell after the stars were spotted leaving a party together.The actress was linked to the Razorlight singer after the pair posed for photographers outside the Vanity Fair and Burberry Portraits party at the National Gallery in London last week. The actress was also spotted sharing a taxi with the rock star, to head to another fashion party thrown by designers PPQ. However, Watson is shocked by the assumptions, and jokes she should create new romance rumors by getting snapped with other famous men, namely Orlando Bloom.Writing on her official website’s blog, the actress says: "I met Johnny Borrell who is modeling for Burberry at the moment and went on to PPQ in the same cab."I’d never met him before so that was great as I’m a big Razorlight fan. But goodness, I am really going to have to watch who I stand next to from now on! "Maybe I should stand next to Orlando Bloom and then we can be said to be dating."
