When Bristol refused to spill the deets on her new man, the hosts of The Bob & Mark Show suggested she say "I'm seeing a guy and he's really great and Tripp loves him and we're having a really good time and we're really good friends." Bristol's response? "Yeah, we can go with that!"

She didn't hold back, however, when it came to the subject of her ex, however. According to Palin, Levi has seen his son"at the most, three times" for "like four hours" since she finished her stint on Dancing With the Stars.

"I've asked Levi to do it many different times, just get it out of the way, just sign over his parental rights, but I don't know if he will or if he wants to right now," she said. "I've asked him to do that many times – just say, 'Hey, look, let's just avoid this custody case that's been ongoing since Tripp was born just get it over with just sign over your rights.'"

But even though Bristol is bitter about her baby-daddy, there is one thing that's putting a smile on her face these days (and no, it's not her new boyfriend)...
