Actress Sofia Vergara has been branded "a horror" by friends of her former fiance Nick Loeb, who claim she was rude and hated sharing the spotlight.

The "Modern Family" actress confirmed last month she and Loeb had ended their two-year engagement, and friends of the businessman admit they are relieved the relationship is over.

"She's a horror," contactmusic.com quoted a source as saying.

Another source added: "I wouldn't say 'bitch' -- but I'm happy to see her go. Good riddance."

The actress has been slammed for her "rude" behaviour during group dinners and it is said that she used to ignore conversation to check social media on her phone instead.

"She only joins the conversation if it's about her," the source added.
