Sofia Vergara and her fiancé, Nick Loeb, got into a New Year’s Eve fight while clubbing in Miami — which ended with her dress ripped down and him being thrown out by security.

Loeb began arguing with the Colombian-born beauty in front of revelers at hot new Miami club Story, where they were being hosted by nightlife king Chris Paciello, whom Vergara dated in the late ’90s.
