Teresa and Joe Giudice Celebrate Their 15th Wedding Anniversary

The "Real Housewives" star posted a photo and called Joe "the love of my life."

— -- In spite of their legal dramas, Teresa and Joe Giudice are still smiling.

The "Real Housewives of New Jersey" stars, who were just sentenced to prison for committing tax fraud, went out to dinner over the weekend to celebrate their wedding anniversary.

"Celebrated our 15 yr Anniversary 10/23/99 With the Love of my Life," Teresa captioned the photo.

It will be their last anniversary celebration for awhile: On Jan. 5, Teresa is expected to report to federal prison in Danbury, Conn., where she has been sentenced to spend 15 months. Upon her release, Joe, who has four children with Teresa, will go to prison for more than three years.

"I was shaking," Teresa said earlier this month of learning her sentence. "At one point, I couldn't even move my fingers. They were stuck. I couldn't open my hands ... my nerves were shot, I've had sleepless nights."
