MIAMI BEACH -

Sofia Vergara's new year was anything but quiet.

According to The New York Post, the "Modern Family" star and her fiance, Nick Loeb, got into a heated argument while celebrating at a Miami Beach nightclub.

Vergara was out with Loeb and several family members at the VIP section of club Story.  Witnesses said the couple, who just got engaged in July, started "pushing and shoving" each other.  Security got involved and Vergara's dress was partially torn.

Four security guards reportedly escorted Loeb out the back door of the club with Vergara following behind him.

But Wednesday the couple is all smiles.  Vergara posted a picture on Twitter having lunch with Loeb.
