SARAH PALIN is cringing with embarrassment over her Alaskan clan popping up on more and more TV reality shows – and she’s afraid it could destroy the “Palin brand,” sources tell The ENQUIRER.


“Sarah worries how seriously she will be perceived if her kin are always out there doing goofball things and turning up on reality shows,” revealed an insider.

The 48-year-old ex-governor has left the door open to running for president some day but fears her family could ruin her potential plans.

On June 19, single mom Bristol, 21, and her toddler son Tripp, were in the spotlight on the first episode of their new Lifetime Network show “Bristol Palin: Life’s a Tripp.” Which was savaged by critics ans got low ratings

Meanwhile, Sarah’s husband Todd, 47, charges into the reality biz Aug. 13. He’ll take part in NBC’s “Stars Earn Stripes,” in which celebrities go to military-style boot camp.

“Sarah’s tried to tell her clanto cool it, but it didn’t take,” said the insider. “It’s become a circus.”

The Palins’ appetite for reality TV fame is nothing new. “Sarah Palin’s Alaska” hit TLC viewers like an avalanche for one season last year. And Bristol followed with a turn on “Dancing with the Stars,” as her famous mom rooted her on.

The critics have already slammed Bristol’s new show, which follows her move into a Los Angeles mansion with her 3-year-old son. It also stars her 17-year-old sister Willow, who serves as baby sitter.

“It’s a new low for anyone who makes the mistake of watching,” blasted Hank Stuev­er of “The Washington Post.”

Confided the insider: “Sarah just wants the whole family. to shut up and get back to Alaska where they belong!”
