Emma Watson petrified to kiss her co-stars

London: Hollywood actress Emma Watson felt uncomfortable while filming romantic scenes with her co-stars Daniel Radcliffe and Rupert Grint in the new `Harry Potter` film. Watson who rose to prominence playing wizard kid Hermione Granger, is currently filming the next installment of the wizard franchise `Harry Potter And The Deathly Hallows: Part 1`.

The star says she gritted her teeth when she was called on to kiss her co-stars, Contactmusic reported. The film is set to hit cinemas next month and features romantic scenes between Watson and both her co-stars. "Getting into character to kiss Dan and Rupert was tough. Forgetting all of our history, and our relationship. Putting all that aside and being in character was pretty hard, it really was. That required a huge amount of professionalism. "I really had to grit my teeth and be like, ``I am Hermione, this is Harry - stop thinking that it`s Emma kissing Dan. It`s not. It`s all good," said the 20-year-old actress who struggled to separate Grint and Radcliffe from their onscreen roles. PTI
