Teresa Giudice says husband Joe Giudice's deportation order is "heartbreaking" for her family. The 46-year-old "The Real Housewives of New Jersey" star spoke out on Tuesday's episode of "Good Morning America" after a judge ruled Joe will return to Italy after his prison sentence. "It's heartbreaking. Very sad," she told host Michael Strahan, adding her four daughters were "really upset" by the ruling. "Adults can handle anything. It's hard for children to go through this." Joe is serving a 41-month prison sentence after pleading guilty to fraud with Teresa in 2014. Teresa, who completed her sentence in December 2015, said the situation has been a strain on their 19-year marriage. "It's very difficult. We've been through a lot. I've gone through ups and downs of being angry," the star said. "I have to stay strong. I have four beautiful daughters and they need their mommy," she added. "The Real Housewives of New Jersey" star and Joe are parents to 17-year-old Gia, 14-year-old Gabriella, 13-year-old Milania and 9-year-old Audriana. Gia and Milania vowed to fight Joe's deportation order in Instagram posts in October. "My dad, who is the best dad in the world, needs to come home," Milania wrote. "We are gonna do everything we can to fight this daddy!! I love you with all my heart buddy #heartbroken." Teresa shared a photo with her four daughters following Gabriella's 14th birthday in October. "Love this pic of me and my girls from Gabriella's birthday! I also love watching American Ninja Warrior Junior with my daughters, it's our new favorite show to watch together!" she wrote.
