Looks like the Palins aren't out of the reality show business yet -- eldest daughter Bristol has just inked a deal with Lifetime for a new 10-episode series called 'Bristol Palin: Life's A Tripp.'

The show, expected to premiere later this year, will feature the 21-year-old single mother adjusting to life in Alaska as she raises her son, Tripp. It will also chronicle her relationship with her famous family: mom Sarah -- the former Alaska governor and controversial vice presidential candidate -- father Todd, and siblings Track, Willow, Piper and Trig.

Lifetime executive Rob Sharenow said, "From the first moment she was thrust into the public eye, Bristol and her son have been the subjects of a huge amount of curiosity and misunderstanding. This show will reveal the real Bristol Palin and her journey as a daughter, a mother and a young woman making her way in the world."

This isn't Bristol's first foray into reality show territory -- she was a contestant on the 11th season of 'Dancing with the Stars,' and was working on a BIO channel series with Disney Channel stars Kyle and Christopher Massey before BIO pulled the plug on the show last year.
