Bristol Palin, the 18-year-old daughter of former Republican vice-presidential candidate Sarah Palin, gave birth on Saturday to a healthy 7 lb., 7 oz., baby boy in Palmer, Alaska.
"We think it's wonderful," said Colleen Jones, the sister of Bristol's grandmother Sally Heath, who confirmed the news. "The baby is fine and Bristol is doing well. Everyone is excited."
The baby's name is Tripp Easton Mitchell Johnston and he was born at 5:30 a.m., according to Jones.
Baby Tripp takes his surname from his dad, Levi Johnston, an apprentice electrician and former Wasilla High School hockey player who has been dating Bristol for three years.
