It Girl Taylor Momsen doesn’t need a fellow starlet as her sidekick - she already has a constant companion in her mother, Colette! The Gossip Girl was spotted with the super-stylish mom in New York’s swanky SoHo Grand Hotel for the He’s Just Not That Into You after-party on February 4. “They were laughing and talking together all night, like girlfriends,” a fellow partier tells In Touch. But the elder Momsen is more than just a party pal to her 15-year-old daughter: unlike other celeb moms, she showed she knows where to draw the line. “Taylor only sipped on water and left promptly when Colette said it was time for them to go at midnight,” the eyewitness adds.
