Men around the world, rejoice. Sofia Vergara is single again after splitting with boyfriend Nick Loeb after more than two years together, Page Six can exclusively reveal.

The Colombian stunner and New York-based Loeb broke up over the weekend following a series of arguments, sources tell us. And, on Monday, she attended the Met Ball alone.

A source told us, “Sofia was confiding in friends at the ball that she and Nick have split. They have been fighting a lot recently and have been on the brink of splitting many times. It is not yet clear if they are over for good, but they are done as a couple for now.”

The actress, who wore Marchesa to Monday night’s Metropolitan Museum of Art’s Costume Institute Gala, got ready at a New York City hotel rather than at Loeb’s apartment, and later attended an after-party at the Top of the Standard with friends.

Another source told us that Vergara and Loeb’s relationship stumbled under the pressure of her growing fame and popularity. Her success on “Modern Family,” and as host of “Saturday Night Live” — as well as her obvious sex appeal — has turned her into one of TV’s biggest female stars.

The couple met at a Golden Globes party in 2010. Vergara said in January that Loeb enjoys red-carpet events. “He loves my career,” said Vergara. “He likes coming to these events. For him, it’s like a hobby to be part of this Hollywood scene.”

But Loeb, who considered running for the Florida state senate last year, is the son of John Loeb Jr., who served President Reagan as ambassador to Denmark. He is the grandson of one of the Lehman brothers and was a partner in his family’s stock brokerage firm.

Other sources say Vergara and Loeb had been on the rocks for some time. Last month, the saucy sex symbol was seen with Loeb at an Upper East Side restaurant, where, “She looked miserable,” sources said. “Sofia looked beautiful, but she did not seem happy with him at all.”
