Bristol Palin is starting to crack under the pressure.
During the October 8 episode of Dancing With the Stars: All-Stars, the single mom burst into tears while rehearsing with pro partner Mark Ballas. "I know you are bummed to have me as a partner," she told him.
Bristol (mom to son Tripp, 3) was inconsolable. "You are not even there," she complained. "You didn't turn up to rehearsal! I feel like you want to go home." The reality star then stormed out of the studio.
If Bristol seemed on edge, it may not be entirely related to the competition, her mother explained via Facebook. "I'm in California today to support Bristol," Sarah Palin, 48, wrote. "I'm sorry to see that she's again getting those annoying death threats and more 'mysterious white powder' sent to her while on DWTS this All-Star season. These threats sure waste a lot of time, production and public resources."
"Do the haters really think this will stop Bristol and Mark and the show's producers from keepin' on keepin' on? Silly critics -- after all these years of goofy antics like this we find these efforts are actually quite motivating!" Sarah added. "Bristol's not letting this get her down."
Dancing With the Stars: All-Stars airs Tuesday, October 9, at 8 p.m. EST on ABC.
