Bristol Palin may have said she plans to wear “the most modest outfits for sure” on Dancing With the Stars, but as of next week, the teen mom, 19, will be stepping out of her comfort zone.

“I’m definitely nervous for next week, because I have to be sexy in the dance and I have to find the sexy in me,” she told PEOPLE backstage Tuesday night after the DWTS elimination show.

The Alaska native, who says she doesn’t weigh herself and doesn’t notice any changes in her body except for toned legs since joining DWTS, will sacrifice any physical insecurities for the sake of staying on the show.

“We’re doing the sexy dance next week, and I have to get into character,” she says. “Dressing sexy will help me get into character more. Next week, I’ll be dressing sexy. This is it.”

Here’s what else you didn’t see:

• An eliminated Margaret Cho said the biggest disappointment about going home after week 3 is missing out on dancing to her most adored jam. “I’m especially sad because next week, we were going to dance to my favorite song, which is “Creep,” by Radiohead, which I love,” Cho told PEOPLE.

• Cheryl Burke was humiliated during the elimination round when she realized she misheard Brooke Burke. Thinking Brooke said Cheryl and partner Rick Fox were safe, Cheryl began cheering and jumping up and down, only to realize Brooke actually said the couple was in jeopardy of being sent home. “This is the most embarrassing moment I’ve had in my whole life,” she said after walking backstage, head in hands. “I feel so stupid right now.”

• “The Situation” made a new friend during a commercial break. Heidi, an adorable 5-year-old girl from Anchorage, Alaska, who was selected out of the crowd to step onto the ballroom and accept a free T-shirt, won over The Jersey Shore star, who ran out onto the stage unexpectedly and placed one of his black leather bracelets with metal stars on the young girl. Later, the two took pictures together backstage.
