Rupert Grint Talks Kissing Emma Watson and Love

Next month's Harry Potter and the Half-Blood Prince finally has some hot kissing scenes!

Rupert Grint finally hooks up with Emma Watson's Hermione Granger in the latest installment of the Harry Potter franchise.

He told the Mail, "We've known each other for 10 years so it was a bit like kissing my sister."

"We were determined to get it right the first time, but our first try was a disaster because we both felt so self-conscious and we couldn't stop laughing."

Although he's a famous 20-year-old celebrity, he says he's still quite "insecure" and shy around the ladies.

"I've never been seriously involved with anyone. I've certainly never been in love. I've always preferred to keep things casual," he said. "It's not that I find it hard to meet girls – they do come up and chat me up from time to time. Sometimes I'm interested, I tend not to go for the prettier ones. I prefer the quirkier types."
