EXCLUSIVE PHOTOS: Levi Johnston's Excellent Beer Pong Adventure

There's nothing like a little game of beer pong after a hard day's work--- at least Levi Johnston thinks so!

RadarOnline.com has obtained these exclusive photos of the former Playgirl model unwinding with some friends at a party in early December.

Levi's friend tells RadarOnline.com that the photos depict a typical night out for the young dad.

"We all used to play hockey for the same team, so after we'd get done with our game we'd usually head over to someone's house and play beer pong," the friend said.

The insider told RadarOnline.com that contrary to internet reports, Levi is still seeing Tripp, the son he shares with ex-fiance Bristol Palin.

"They're both so arrogant, they fight all the time," he revealed. "She'll freak out about something, and then he'll freak out about something and then they'll resolve it. He'll go and see the kid...they're he and Bristol not on the best of terms but they're getting along right now."

The insider also says that contrary to reports, Bristol's famous mom, Sarah Palin, stays out of the drama.

"She stays out of it. She doesn't really want all of that to affect what she's trying to do right now. She's a good person."

The friend, who says he's known Levi and the Palin family for "eight or nine years" says Levi also likes to spend his downtime in the mountains above his home in Alaska.

"I'm in college and Levi does part time work as an electrician's apprentice, but on the weekends we like to go snow machining and hunting up in the mountains. We have a good time."
