In a video in which she holds her 20-month-old son, Lorenzo, she opens an off-camera container of pink balloons that fill the screen. "Oh, my goodness! We're having a girl! Yay! Oh, God, kill me," she jokes, adding, "I don't know how I feel about it, I'm terrified, but we're really, really excited."

Polizzi, 26, had told "Extra" last month that "we kind of want two boys" because "I'm not ready to have a miniature me. I don't need a diva telling me what to do. I'm not ready for that."
