She calls boyfriend Marc Singer "amazing" and a great kisser

Jane Krakowski’s life is different since meeting Marc Singer. And the 39-year-old star of 30 Rock tells PEOPLE it’s “love.”

“It changed my life,” Krakowski said of meeting Singer at a Cinema Society screening of Children of Men in late 2006. “We sat and talked forever that night.”

On their first real date, “we were supposed to go to dinner,” she added. “But we ended up just having drinks at my place all night long. We never made it outside!”

At the opening of Michael Kors’s new downtown Store in SoHo Monday, Krakowski, opened up about what attracted her to the documentary filmmaker. “He was the most interesting person I’ve met,” she said. “He’s very young, and he’s lived many lives already.”

Handsome and brilliant, yes. But is he a good kisser? “Great,” said Krakowski. “And he’s an amazing person.”
