Rachel Bilson "is not dating" Chace Crawford, her rep tells UsMagazine.com.
Life & Style claims "there was lots of flirting going on between the two of them" during a dinner with a group of friends at The Lion in NYC last Friday.
"She's friends with his manager and has known Chace for a while," her rep explains to Us. "The dinner was with a bunch of people, and it was simply a friendly dinner. I can say with 100 percent certainty they are not dating.”
Bilson, 29, and actor Hayden Christensen called off their engagement earlier this summer.
