Bristol Palin is a mom! The 18-year-old daughter of Sarah Palin reportedly gave birth to a 7 lb., 7 oz., baby boy in Palmer, Alaska on Saturday.

The baby's name is Tripp Easton Mitchell Johnston.

The baby's father, Levi Johnston, says he plans to marry his fiancée Bristol in 2009 and they will raise the child together.

We bet Bristol will be a hockey mom in no time! Wink, wink!
