They may have starred in the 2009 romcom, The Proposal, but there are no fireworks in the air for Sandra Bullock, 46, and Ryan Reynolds, 34.

Though the pair partied the night away on New Year's Eve at a bistro in Texas owned by Bullock, the newly single actors are not dating. "A group of old friends that included Ryan and Sandra spent New Years together," explained a rep for the actress to The Daily Mail. "They all had a great time ringing in the New Year as they have in the past … as nothing more than friends."

Reynolds filed for divorce from wife of two years, Scarlett Johansson, just last month, and Bullock split from her ex, Jesse James in a highly public divorce last June. Bullock and Johansson also have a history, of sorts. The two shared a deep onscreen kiss at the 2010 MTV movie awards, after which Bullock declared that "Scarlett is a great kisser." —KIMBERLY STEELE
