In one of the shots, the 19-year-old single mother posed seductively with professional partner Mark Ballas, wearing a lacy, black dress with fringe accents.

Palin, who calls herself "naturally shy," recently predicted to People magazine that she would be"the most dressed contestant" this season.

"That's how I am, and that's how I want to dress," she added to US Magazine.

Palin, along with the other 11 star contestants, will make her ballroom debut when Season 11 of "Dancing with the Stars" premieres Sept. 20 at 8 p.m. ET on ABC.
