Actress Jaimie Alexander has confirmed that she's dating Twilight star Peter Facinelli.

The Nurse Jackie co-stars, who became friends while working on the movie Loosies and were romantically linked for the first time earlier this year after sharing photos of a Paris vacation they took together on Twitter.

Speaking to People magazine, Alexander said: "We've been friends forever and had a lot of mutual friends and we reconnected in the middle of the year. It was one of those things where I'd been single for a very long time and he was going through a lot. We sort of bonded.

"It's very new to me and it's scary, but it's also something we don't want to give up on because I know how it makes me feel in my heart... It makes me feel really good. He's a good guy with a great family and I couldn't be any luckier."
