A rep for both stars has confirmed their breakup.
Lively, 23, and Badgley, 23, have been linked since 2007, though they initially denied their romance, saying they were just friends and costars. Since 2008, however, the two have gone public with their relationship, appearing together at events and, often, hand-in-hand in New York City.
Most recently, the former couple went shopping for candles together at Henri Bendel in New York last weekend.
