Sarah Palin Talks About Death Threats to Bristol

Sarah Palin has a message for the "haters" who sent daughter Bristol Palin threatening packages on the set of "Dancing With the Stars" last week: Don't waste your time.

The proud mom and former vice presidential candidate took to her Facebook account today and slammed whoever anonymously sent "mysterious white powder" to the "DWTS" all-star season set in California.

The package reportedly contained a note threatening the "Dancing With the Stars" producers if Palin is not removed from the show.

"These threats sure waste a lot of time, production and public resources; but do the haters really think this will stop Bristol and Mark and the show's producers from keepin' on keepin' on?" Palin wrote.

The FBI and the Los Angeles Police Department have confirmed that they are investigating a suspicious package that was sent to the Hollywood set last week along with the threatening message targeting the 21-year old contestant, according to TMZ.

A similar threatening package was sent addressed to Palin in 2010 when she first appeared on the program.

"Silly critics - after all these years of goofy antics like this we find these efforts are actually quite motivating!" Palin added.

The former Alaska governor traveled to California today to cheer on her daughter in the competition's third week. Bristol Palin and her partner, Mark Ballas, face "double elimination."

A get-out-the-vote pro, the elder Palin urged her supporters to dial in for her daughter.

"I'll be sure to post the call in number and voting instructions later today before the event," Palin said. "It means a great deal during this fun and highly competitive event, and it's sure appreciated!"

For her part, Bristol Palin, who stars in her own reality-television program with her toddler son "Bristol Palin: Life's a Trip," appears to chalk up the threats to her new-found fame.

"Hey, the haters will hate anyway; the critics will criticize, so you might as well dance!" she said, according to Sarah Palin.
