Teresa Giudice's 'RHONJ' Costars 'Blindsided' By Shocking Cheating Scandal

Fans were shocked by RadarOnline.com's exclusive photos of Teresa Giudice holding hands with young hunk Blake Schreck — and so were her The Real Housewives of New Jersey costars, RadarOnline.com can exclusively report.

"They had no idea she was dating someone else," a source close to the cast told RadarOnline.com exclusively. "She kept this away from the show. She didn't tell the ladies at all."

However a source close to the RHONJ ladies, including Margaret Josephs, Dolores Catania and Danielle Staub, were happy she has seemingly moved on from her imprisoned husband Joe Giudice, who as RadarOnline.com exclusively reported, is slated to be deported from the country. (His appeal against the immigration judge's decision is currently pending.)

"They said, 'Good for her, he's hot!'" said the source.

The source insisted Teresa's sister-in-law, Melissa Gorga, had an inkling that she was dating someone else while her husband remained in prison.

"She won't be surprised at all," the source claimed.

As RadarOnline.com exclusively reported, Teresa, 46, was caught holding hands and touching 26-year-old New Jersey native Schreck in Miami on February 16.

"This is a story about someone helping a woman who had some wine and was wearing high heels to her car," her attorney, James Leonard Jr., said in a statement. "That's what you see in those pictures. There is no cheating, no divorce, no scandal and no story."

Leonard also said the interaction between Teresa and her boy toy was "brief."

However, RadarOnline.com can reveal the pair spent the entire long weekend together.

The spokesperson also previously denied RadarOnline.com's exclusively report that Joe was going to be deported from the country — but an immigration judge later announced his decision to deport Joe , and now the jailbird is fighting with an appeal.
