Last season on Dancing with the Stars, Nick Carter (!) cries while discussing his past home situation before joining the Backstreet Boys. 'The boys saved me,' he says. This is in the 'most memorable year' episode. I think also in a later episode when discussing his sister's death via OD.
Honestly it seems at least half of the contestants cry while recounting their Most Memorable Year. Steve Irwin's daughter Bindi sure did (ya think and who wouldn't?), I think Tamar Braxton did. Rumer Willis the season before that.
