Hang in there, Gia!

The 16-year-old posted a photo on Instagram Monday night with her father, Joe Giudice, in honor of his 45th birthday.

The married father-of-four rose to fame on Bravo's The Real Housewives of New Jersey in 2009 and is currently serving a 41-month prison sentence after pleading guilty to nine counts of mail, wire, bank, and bankruptcy fraud in 2014. Wife Teresa Giudice already served 11 months behind bars for the charges.

In her post, Gia said, "Happy birthday daddy. Love and miss you so much can't wait for you to make me endlessly laugh everyday."

Adorable!

According to Us Weekly, however, Joe could be out of the slammer as early as March 2019. Due to his inmate status with the Federal Bureau of Prisons, this now means the Italian reality star would get to see his wife and children five months sooner than expected.
