Casually dressed in a fuchsia track suit, Giudice quietly told PEOPLE that she's doing "OK" as she entered the taping, but a source says the reality TV star isn't in good spirits.
"She's not doing well," a source who knows Teresa revealed to PEOPLE. The star has kept a low profile since she and husband Joe Giudice, who was sentenced to 41 months, pleaded guilty to mail, wire and bankruptcy fraud.
Husband Joe arrived separately to the taping. Wearing sunglasses, a light brown suit, pink button-down shirt and tie, he didn't speak as he headed inside.
According to an onlooker inside the reunion taping, Teresa "looks upset. Normally at a thing like this, she would be on fire. But it's quiet. Everyone is being a little more cordial."
Teresa's brother Joe Gorga was also present at the taping. Clad in all black, he was spotted hugging production assistants, who were overheard telling him he looked good.
At the end of the taping Sunday, host Andy Cohen told PEOPLE it was, "Emotional. Very emotional." And according another source inside, Teresa and Joe seemed "down, out of it. Like they know they're f---ed."
On Friday, both Joe and Teresa stopped by Bravo's Watch What Happens Live set to tape their first post-sentencing interview with Cohen, which will air Monday at 9 p.m. ET on Bravo.

On Saturday, Teresa announced she'd be canceling a wine party for her Fabellini brand. But in spite of more than a year of legal woes, she has remained committed to RHONJ, telling PEOPLE, "This is my job and I want to keep going."
