Peter Facinelli's friendship with Jaimie Alexander has blossomed into romance
. Something Alexander says has her feeling good if not a little scared.
"We've been friends forever and had a lot of mutual friends and we reconnected in the middle of the year," Alexander told PEOPLE Thursday night at the Tommy Hilfiger and GQ
"Men of New York" event at Hilfiger's 5th Avenue flagship in New York. "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."
Facinelli, who split with Jennie Garth
in March, and Alexander met on the set of Loosies
, which Facinelli co-wrote, and went on to work together on Nurse Jackie
"It's very new to me and it's scary," Alexander said of their relationship. "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."
Alexander can even count on her beau for fashion advice.
"Peter put this coat with this dress!" she said of her Catherine Malandrino coat and Naeem Khan gold frock. As for Facinelli's own style, Alexander said "he picks out his own clothes, and I think, of course that he looks handsome in everything."
Hilfiger donated 20-percent of the evening's sales to the Mayor's Fund to Advance New York City for Hurricane Relief.
