Sofia Vergara went shopping with a friend in West Hollywood yesterday. She stepped out just a day after filming on the fourth season of Modern Family got started in LA. Sofia was on set with her onscreen son, Rico Rodriguez, whose 14th birthday coincided with the first day of production. The cast is back to work following contract negotiations that ended with Sofia, Julie Bowen, Ty Burrell, Jesse Tyler Ferguson, Ed O'Neill, and Eric Stonestreet all receiving raises. It's just one more cause for celebration for Sofia, who recently marked her 40th birthday, got engaged to boyfriend Nick Loeb, and was nominated for a best supporting actress Emmy. She was also just named the winner of our 2012 PopSugar Bikini Bracket — check out Sofia's hottest bikini moments!
