Emma Watson denies dating a rock star. The 'Harry Potter' star, who play Hermione Granger in the hit movie franchise, slams reports that she's dating Johnny Borrell, lead for the British rock group Razorlight.

News of that the two were dating surfaced when the 17-year-old actress has been spotted with Borrell at the Vanity Fair and Burberry Portraits Party in London Monday. Watson has written on her official website that although she's a big Razorlight fan, she is not dating the rocker.

She writes: "I also 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."

She then went on to joke about the guys she should be seen next with, "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!'"
