Levi Johnston wants full custody of son with Bristol Palin - report

Levi Johnston reportedly has decided to pursue full custody of three-and-a-half-year-old son Tripp in light of seeing how Tripp behaves on mom Bristol Palin's reality show "Life's a Tripp." On the show, Tripp has been seen talking back, cursing and calling his Aunt Willow a f***** on one recent episode.

Johnston tells TMZ he's "disgusted" by his son's behavior on the show and feels that Tripp is getting "no real parenting." Johnston adds, "I love my son more than anything and I will do whatever it takes to make sure he is raised the right way."

Reportedly Johnston has picked up the paperwork from the Wasilla, Alaska courthouse to pursue full custody. Meanwhile, Bristol is about to start her second stint on "Dancing With the Stars."
