Three is apparently not a crowd for Bristol Palin and her new reality TV costars
Kyle and Chris Massey.
The single mom, 20, moved out of her Arizona digs and back to Los Angeles with her son Tripp, 2, to live with fellow former Dancing with the Stars
contestant Kyle, 19, and his brother Chris, 21, in an experience Kyle calls "a lot of fun."
"Kyle and Bristol hit it off from pretty much the first day they met," Chris tells PEOPLE. "We all became really good friends. Over the whole course of the show, we only got closer and closer. Both of our families connect well. It's one big happy family."
"It's definitely going to be a ride," adds Kyle, who recently performed at Hugh Hefner's birthday party with Chris as the Massey Boyz hip-hop duo. "What you can expect is just three friends taking on the world."
Both brothers kept mum on whether or not the topic of Palin's new chin
would be addressed in the series. On that matter, Kyle would only say, "You're going to see a lot of smiles on the show."
The BIO channel has ordered 10 half-hour episodes of the as-of-yet untitled documentary series, which is set to air at the end of this year.
