Kim Kardashian's friend and former 'Dancing With the Stars' partner, Mark Ballas, isn't the least bit worried that ugly cheating allegations will alter the reality star's wedding or hurt her image. But while he doesn't believe the rumors are true, he tells me she may have erred in fighting back so forcefully.

"Kim probably shouldn't have said anything, shouldn't have fought back," Mark explains. "But sometimes it's hard to just say nothing. I think it's the best thing to do, but if someone was saying that about me, I'd fight back."
