Watson was 'desperate' to get Grint kiss over with
The actress, who plays swot Hermione Granger in the wizard franchise, locks lips with Grint - Ron Weasley - in the forthcoming instalment, Harry Potter and the Half-Blood Prince.
But Watson admits the scene was anything but sexy - insisting she couldn't wait to get the smooch over and done with.
She tells Jonathan Ross, "I pounced on him, I was so desperate to get it over with."
The comment will come as a devastating blow to Grint, after he admitted he and fellow co-star Daniel Radcliffe have competed for Watson's affections since they started filming the movie aged 11.
He told FHM magazine, "Emmas a pretty girl. Have Daniel or I ever hit on Emma? Well, shes quite popular with the cast. As for who has the worst crush on her - me or Radcliffe - Id rather not say."
