Chelsea Handler and new boyfriend Andre Balazs took their romance public this past weekend in New York City, UsMagazine.com reports. The couple, which has been quietly dating since January, was at the Boom Boom Room this Saturday celebrating the launch of Handler's fourth book, Lies That Chelsea Handler Told Me.

There were a bunch of other famous faces at Handler's book party including Katie Couric, Lucy Lui, Vera Wang, Josh Hartnett, Michelle Trachtenberg and Carla Gugino. And keeping in line with Handler's love of Belvedere vodka, guests sipped on Belvedere Bloody Mary & Pink Grapefruit cocktails.

And what does Handler gal pal, Heather McDonald, think of the talk show host's new man? "He's a babe. He's very successful and he's very nice. I think she's met her match," McDonald recently told E! News. "He doesn't put up with her, but in a fun way, which she loves. Chelsea likes when you don't put up with her too much."
