Bennett was in labor for five hours before her 5-pound, 15-ounce baby was born Monday.
The first-time mother is reportedly doing well.
In a news release, the 20-year-old says she's "so excited to finally see my little angel." Bennett adds, "Man, does she have lungs on her. I guess she's gearing up to be the next American Idol."
Bennett is scheduled to release her first Christmas CD, "A Royal Christmas," on October 14th.
