Sofia Vergara's ex-fiancé claims they only split because she didn't want to have a baby.

The 'Modern Family' actress parted ways with Nick Loeb in May amid rumours she was fed up of him using her for her fame and has since moved on with 'Magic Mike' heartthrob Joe Manganiello, but the businessman believes they would still be together if she wasn't ''taking advantage of her 15 minutes of fame.''

Asked about the Emmy Award winner, the entrepreneur told In Touch Weekly magazine: ''She's focused on her career. The most important thing for me is to get married and have kids.''

He added: ''I completely understand. She's at the height of her career, and, as she says all the time, she's taking advantage of her 15 minutes of fame because who knows how long that will last.''

The 'Chef' star, who has son Manolo Gonzalez, 21, with ex-husband Joe Gonzalez, had an awkward encounter with Nick at the Angel Ball in New York City on Monday night (20.10.14) when he tapped her on shoulder while she was being interviewed.

A source told PEOPLE.com: ''Obviously, she wasn't jubilant about turning around and hugging him. It was more like she brushed him off and just tossed her hair and kept her cool. I wouldn't say she was overly happy [to see him].''

Shortly after their split, the Colombian actress, 42, started dating Joe, 37, and she recently said: ''He's a great guy, he's very funny. And he's very entertaining which is very important for me because I need to be with somebody that knows how to have fun because I like to have fun.''
