WENN 1 / 5

Romance from behind bars! Joe Giudice is doing everything he can to keep the flame burning with his wife Teresa, despite the fact he's in prison.

His passion is coming via the written word.

The "Real Housewives of New Jersey" star told Entertainment Tonight that her man sends her x-rated emails from Fort Dix Federal Correctional Institution.

"I'm not going to say what the emails say," she said. "He's doing good. You know, being positive, and we're just both taking one day at a time."

"He's eating right ... because you know, it's good," Teresa added. "He said it's good. He's getting his mind focused and he's not drinking. I guess he was drinking a lot."

They'll have to get used to this life for a wife, too. Joe is just over two months into a 41-month prison sentence for fraud. He's expected to be released five months early.

Teresa, Joe and their four daughters — Gia, 15, Gabriella, 11, Milania, 10, and Audriana, 6 — know a thing or two about being separated. Teresa spent 11 months locked up in Connecticut's Danbury Federal Correctional Institution for similar fraud charges. She was released just before Christmas of 2015.

"We're married 16 years and I just can't wait for him to get home," Teresa said on June 29. "I think it's just going to spice up our marriage even more. Yeah, when I came home, it's like falling in love all over again."

While she was in locked up, Teresa also tried to keep the spark alive. At the time, Bravo was filming a special about Teresa's time in prison and viewers heard phone conversations between her and Joe. During one conversation, Teresa apparently pleaded with him to have phone sex with her, but her husband laughs it off. She said she had heard her fellow inmates involved in a little hanky panky, but she hadn't partaken.

After she was released, she told Us Weekly that "[Joe] was only allowed to come every other weekend, and every time he came to see me, our daughters were always there. The last 15 minutes, then our daughters would leave and then we would have only 15 minutes alone time.

"We definitely made out and kissed and held hands, because you are allowed to kiss in the beginning and at the end," she continued. "Not as long as you want, depending who's on, depending which officers are on."

For now, though, emails will just have to do.
