Reports emerged in May that the Modern Family actress had split from Loeb after dating for two years.
"Sofia was confiding in friends at the [Met Ball] that she and Nick have split," a source claimed.
WENN now reports that the couple have reconciled, after being spotted together at a New York cafe earlier this week.
The pair were later seen on Thursday (June 7) dining at a restaurant in New York's Meatpacking District.
Vergara has yet to comment on the status of her and Loeb's relationship.
