'Real Housewives' Star Joe Giudice Admits to Drinking Up to 4 Bottles of Wine a Night

— -- "Real Housewives of New Jersey" star Joe Giudice admitted to Andy Cohen in their sit-down interview that he does have a drinking problem.

The reality star, who was just last week sentenced to three and a half years in jail for fraud, said in a few teaser clips for tonight's part 2 of the full interview, "I might have a little problem, yeah. I'm not going to lie."

"I think I used to drink only on the weekends. Now I drink everyday," he said of how the problem has gotten worse recently. "But, just wine, I don't drink anything else really."

In fact, Joe, 42, said, "I could easily do two, three bottles, four bottles easily" a night.

"You know with another person," he said. "Sometimes two by myself. Well one bottle's like sucking a bottle of milk, it's like nothing ... It does help me sleep. It's either that or I have to take a pill and I don't want to take a pill."

Joe Giudice and his wife Teresa were sentenced last Thursday and sat down with Cohen the next day to speak out for the first time about their upcoming jail sentences. Teresa got 15 months and the couple's sentences will be staggered. They are parents to four daughters -- Gia, Milania, Gabrielle and Audriana.

Part 1 of the interview aired this past Monday and part 2 airs tonight at 9 p.m. on Bravo.

Joe also talked about the chance of him being deported since he's not an American citizen.

"I'm going to worry about that when the time comes," he said.

As for if he may have to move the family to Italy, where he's from, he said, "It's not such a bad thing."

Teresa, 42, also said she doesn't resent Joe in any way, since he admitted that the fraud was mostly his doing. She starts her sentence on Jan. 5.

"I don't think he meant to hurt me in any way," she said of getting jail time. "I think it's a learning lesson for both of us ... I know he didn't mean to hurt me in any way ... Since [the sentencing], he's been feeling bad and keeps coming up to me and hugging me."

Joe said he does feel guilty about dragging his wife into his legal mess.

"But at the same time what am I going to do. I did everything I could to get her out of it, but didn't work," he said.
