Here's How Teresa Giudice's Daughter Gia Is Celebrating Her 14th Birthday

Source tells E! News, "She's really got her life in order right now...Everyone's really proud of her."

It's a bittersweet day for Gia Giudice.

The Real Housewives of New Jersey star is celebrating her 14th birthday today, however, there's one very important person missing from the festivities—mom Teresa Giudice.

Unfortunately, Gia's special day comes after Teresa surrendered for her prison sentence early Monday morning, and while we're told that Gia is spending her day just like any other day (like going to cheer practice, for example) E! News also learns that the young reality star has some exciting things planned for the big 1-4 in the coming weeks.

"Her friends are throwing her a big party this Saturday," the insider tells us. "Next weekend, she'll have another celebration with her bandmates in 3KT. Everyone wants to celebrate with her."

The source also noted that Gia is holding up phenomenally considering the recent circumstances. "She's really matured so much just in this past week. She's got it all together. Two days a week, she mentors kindergarteners through third graders after school. She has cheer practice three days a week and she has her girl group.

"She's busy, but happy. She's really got her life in order right now...Everyone's really proud of her."

Gia tweeted Sunday night, "support system is unreal #soblessed."

The 42-year-old Real Housewives of New Jersey star, who is currently serving 15 months in federal prison for fraud charges, spent her final hours as a free woman with her husband Joe Giudice as well as the couple's four daughters, Gia, 14, Gabriela, 10, Milania, 8, and Audriana, 5, enjoying quality family time while ensuring that her loved ones are prepared for her absence. 

"She spent Sunday at home with the family getting the house in order," a source told  E! News. "She wanted to make sure everything was organized before she left. Her priority was making sure her daughters' schedules and routines would be disrupted as little as possible."

Upon completion of her 15-month sentence, Teresa's husband of 15 years, Joe, 42, will serve 41 months in prison (their sentences were staggered to ensure that one parent remained at home with their children). Joe then faces the possibility of deportation, as the native Italian is not a U.S. citizen.
