Breakups & HOOKUPS!

While some A-listers head for splitsville, others are getting hot and heavy...

Joe & Caitlin RED CARPET OFFICIAL

Sofía who? Five months after announcing his divorce from wife of seven years Sofía Vergara, Joe Manganiello made his first public appearance with new gal pal Caitlin O'Connor at the Children of Armenia Fund gala in NYC on Dec. 9. The True Blood star, 46, was initially linked to Caitlin, 34, when they were spotted leaving an LA gym together in September. "Sofía's feelings were hurt that he moved on so fast," admits an insider, adding that the 51-year-old has since happily moved on with orthopedic surgeon Justin Saliman herself. "But maybe Joe dating again is what encouraged her to do the same!"

Eric & Janet OVER AFTER 26 YEARS

On Nov. 22, Janet Leigh Holden filed for divorce from Eric McCormack following 26 years of marriage. The pair - who are parents to Finnigan, 21-met in 1994 on the TV series Lonesome Dove, where he was an actor and she was an assistant director, and wed three years later. Though she cited irreconcilable differences as the reason for their split, Eric, 60, previously credited Janet, 70, with keeping him grounded during the height of his Will & Grace fame: "I conducted myself as a much better human being because I was already married when all that came along."
