Levi Johnston is set to file for joint custody of his 10-month-old son Tripp with his high school girlfriend, Bristol Palin.

Johnston told The Insider, "At the end of the month I'm going to file for joint custody of Tripp."

The decision came after Johnston had trouble visiting Tripp over the weekend. The current custody agreement is "Not working. I'm done," he says. "It's going to have to go to court. They just finally pushed me over the edge."

But now that Levi's got so many gigs (including showing off his "wang" in Playgirl), will he be able to handle joint custody?
