Emma Watson's wet Harry Potter kiss

Emma Watson was "soaked with a vat of water" prior to her 'Harry Potter' kiss.

The 21-year-old actress - who has played Hermione Granger in the wizard franchise since she was just 10 - smooches co-star Rupert Grint in 'Harry Potter and the Deathly Hallows: Part 2', and admitted the pair were worried about the hotly-anticipated moment "living up to all the hype".

She said: "We knew that we'd been building the anticipation of this moment for 10 years. It'd been going on for so long. Rupert and I really wanted to make sure it lived up to all the hype. We were nervous, it was awkward, but I think we did the moment justice.

"The funny thing about it is the moment before we kissed, we get soaked with a vat of water so we had that going on as well."

Emma - who broke down in tears as she addressed fans at the premiere of the final movie in the franchise at London's Trafalgar Square - explained she will "really miss" living in the wizardly world of her alter-ego.

Addressing co-stars, Rupert Grint and Daniel Radcliffe - who play Ron Weasley and Harry Potter respectively - she added "I will really miss those boys. I will really miss Rupert and Dan. I will really miss being Hermione and living in her world."
