After she was eliminated Tuesday on ABC's Dancing With the Stars, Florence Henderson tells UsMagazine.com she "was a little surprised, but you know I've watched this show since it began, and I've seen absolutely shocking things happen on it, so somebody has to go."

Palin, 19, who scored the lowest on Monday's show for the jive, tells Us, "I'm so relieved. It is like a big weight was lifted off my shoulders. I was scared and nervous going into the night, but we got through so that's very exciting ... I was definitely surprised and shocked when they said we were safe... with our low scores and stuff, it was pretty stressful."

She says she thinks that voters saw her "rawness and vulnerability" and that's why they kept her in.

"I'm just so thankful that they kept me another week and they see potential in me obviously," she tells Us. "Hopefully I can prove that I can be a performer." Bristol says her confidence is now "pretty high ... but I know we've got lots of work to do for next week, and I'm ready to go practice."
