According to the New York Post, Bosworth had a big dispute with her boyfriend, James Rousseau, and left him alone to go party with her friends in New York City.
A source said of the squabble, "He was trying to hail a cab, but he couldn’t get one fast enough for Kate. She then started walking away to hail a cab herself. She was fuming."
The starlet was spotted later with Helena Christensen at the Street’s Angels and Kings nightclub in the East Village. Bosworth, 24, and Christensen, 38, left the club in a limousine.
