Bristol Palin has had enough of the lower 48. The 20-year-old, who bought a house in Arizona and then moved to Los Angeles with son Tripp, 3, is now back in Wasilla, Alaska, and living in an apartment on Mama Grizzly Sarah Palin's property.

"I wasn't really into the Hollywood thing," Bristol told InTouch magazine. "I just realized I was over it and I wanted to come home."

The former "Dancing With the Stars" contestant is now back at her old job working in a dermatologist's office, ABCNews.com confirmed.

Palin told the magazine that a verbal brawl at Los Angeles bar Saddle Ranch, which was caught on camera, contributed to her decision to go back to her roots.

While she was riding a mechanical bull, a heckler yelled out, "Did you ride Levi like that?" referring to Levi Johnston, the father of Bristol's young son. The man went on to call her mother, the former Alaska governor, a "whore." After being bucked off the bull, Bristol walked over to confront the heckler. A video of their exchange shows the two talking for several minutes about why he doesn't like Sarah Palin.

Son Tripp also influenced her decision. "He's going to be starting preschool soon," she told the magazine. "So we needed to settle into a routine."
