SOFIA Vergara and fiance Nick Loeb are in therapy.

"She decided they needed professional help before she would walk down the aisle," a source said. "They had their first session over the phone - and so far, so good!"

Sofia's son doesn't want his mom to marry Nick.

"Nick's hair-trigger temper has Manolo scared to death," a source American tabloid the National Enquirer.

"Manolo desperately wants to like the guy, but violence seems to follow Nick around. Manolo is extremely protective of his mother, and now he's afraid for her safety. He believes Sofia should slam the brakes on her wedding plans immediately."

Problems started after Loeb, a 37-year-old businessman and banking heir, rang in the new year with Sofia, 40, and Manolo at the Delano hotel in Miami's trendy South Beach.
