Loeb was reportedly thrown out of club for a fight with the sultry TV star in Miami during the wee hours of the first day of 2013, the New York Post reported.
Loeb and Vergara got into a serious argument in the VIP section of Story, a Miami Beach club. Sources said that "some pushing and shoving" went on as part of the fight. Apparently, it all started over a friendly photo op Vergara engaged in with a fan.
"Nick appeared to get really angry after Sofia took a picture with a stranger, and started screaming at her. Nick had to be pulled off Sofia by security. Her dress got torn in the melee. This happened right in front of everyone in the VIP section," an onlooker said.
"Four security guards grabbed Nick and threw him out of the back door of the club, with Sofia following behind."
The brawl apparently happened in the presence of Vergara's family, including her son Manolo. They had all been out celebrating New Year's Eve at the Miami Beach club.
This was after the couple took part in the countdown to 2013 at Delano Hotel and even enjoyed a midnight kiss as part of the celebration.
Vergara, who was married from 1991 to 1993 to Joe Gonzalez, has been engaged to Loeb since July.
