"Dancing With the Stars: All-Stars" received a suspicious package targeted at Bristol Palin, according to The Hollywood Reporter.

The package contained a note that read "This is what will happen to you if Bristol Palin stays on [the show]," TMZ reports.

According to THR, law enforcement determined the white powder included in the package was harmless, but it's still being treated as a serious investigation.

Palin joined the cast of "All-Stars" after making it in the finals of "Dancing With the Stars" Season 11. During her original season, Palin was also targeted with a suspicious package. Palin's participation in the program in 2010 also reportedly caused a man to shoot his TV with a shotgun.

On "All-Stars," Palin is partnered with her Season 11 partner Mark Ballas. The celebrity dance competition is currently in its third week of competition.
