2010's Surprising Celebrity Breakups

Dec. 14, 2010— -- It's been a rocky year for celebrity romance -- young and old alike.

Over the past two days, at least three star couples have split. The latest: Scarlett Johansson and Ryan Reynolds.

"After long and careful consideration on both our parts, we've decided to end our marriage," the couple said in a statement released by Reynolds' publicist today. "We entered our relationship with love and it's with love and kindness we leave it. While privacy isn't expected, it's certainly appreciated."

Johansson, 26, started dating Reynolds, 34, in 2007. The couple announced their engagement in May 2008 and married that September in Vancouver, B.C.

On Monday, People magazine reported that one of Hollywood's young golden couples, Zac Efron and Vanessa Hudgens, have called it quits four years after they met on the set of "High School Musical."

Efron, 23, recently spoke about his relationship to the 22-year-old Hudgens, saying their love was "exactly how it should be. It's real."

Michael C. Hall and his wife, Jennifer Carpenter, have been having a rough time too. The co-stars of the cable series "Dexter" have been married for two years -- on television they played brother and sister -- but their publicists let it be known Monday evening that, "having been separated for some time," they were calling it quits.

Sadly love is not enough, as Liz Hurley knows all too well.

After a U.K. tabloid published a picture of the 45-year-old actress-model kissing Australian cricket player Shane Warne, she announced on Twitter that she had separated months before from husband Arun Nayar.

"Not a great day," Hurley tweeted Sunday. "For the record, my husband Arun & I separated a few months ago. Our close family & friends were aware of this."

Hurley married Nayar, an Indian-German textile heir and software entrepreneur, in 2007, in two lavish ceremonies -- in a castle in England and a palace in India. The couple then moved with Hurley's 8-year-old son Damian to an organic farm in Gloucestershire, where she has been working on a line of healthy snack foods.

Warne also posted a statement on his website Monday, revealing that he and his wife Simone had split a while back.

"It is a private matter so we did not make it public," he wrote. "We remain friends and will continue to be good parents.''

After Hurley and Warne met at a racing event in June, they began exchanging flirty messages via Twitter.

"Hello new Australian friend, how nice to have met you & in such sexy surroundings. I like the papers saying we're old friends...'' Hurley wrote on July 29.
