After only a few weeks on air, Bristol Palin’s reality show “Life’s a Tripp,” has been bumped from it’s 10 p.m. timeslot back an hour to 11 p.m. It will air behind a new episode of “Dance Moms” — an a repeat of the same episode of “Dance Moms.” The ratings for the show have not been good, with the first episode drawing in only 726,000 viewers. The episode of “Dance Moms” from that same night brought in 1.8 million viewers. Needless to say, Bristol’s reality show doesn’t seem long for this world. We’ll see how long Lifetime keeps airing it.
