After confirming that he and fiancee (and the mother of his son) Bristol Palin, daughter of Alaska governor Sarah Palin, had broken up, Levi Johnston is appearing on Good Morning America today. The new father (son Tripp was born in December) claims they broke up a week ago and suggested it's not over, "We'll just remain friends for now. We're both cool with that decision, and we'll see... We were just, we were in a fight. And trying to see if we can make things work. But this is what it kind of ended up turning into... It's just us not, me not being mature enough, or something, and having a kid and thinking ... it could be better -- better for us to separate for a while." Spoken like a 19-year-old! As for Bristol, she took her mom's place at a state mini golf event while the Governor was helping a Girl Scout troop sell cookies (the troop was robbed!) at a supermarket. Palin, with kids Willow, Piper and Trig plus grandson Tripp in tow, told People that her 18-year-old daughter was doing great.
