Bristol Palin’s reality show has tanked big time, but surprisingly that’s the least of her worries. Now she could be losing custody of her son! After watching “Life’s a Tripp,” baby daddy Levi Johnston has decided that Bristol’s a bad mom and he can do a better job parenting the tot.

Hardly anyone is watching the Lifetime series, but the few who do have noticed that the three-and-a-half-year-old Tripp appears to be an undisciplined brat who swears, refuses to obey adults, and calls them names. All this has come to the attention of his dad Levi Johnston, who told TMZ that he’s “disgusted” and thinks the child is getting “no real parenting.”

He may have a point, since Palin herself has said on the show, “I’m doing a terrible job disciplining Tripp.”

Johnston thinks his son “deserves a better family” than his ex is providing. He added, “I love my son more than anything … and I will do whatever it takes to make sure he is raised the right way.”

Johnston was spotted at the Wasilla, Alaska, courthouse getting the paperwork to file for custody of the child, but will anything really come of this? After all, Bristol’s mom Sarah Palin used to be governor of Alaska and still has some pull back there.
