At first, the Dancing With the Stars dancer expressed some shock that Santa was not real and joked, "I'm still waiting for Santa to come!" The 36 year old then shared her story.

"I'll tell you when I first realized he was not real. I kept asking my parents back in Ukraine. I remember hearing someone at the door so I ran downstairs, and I saw my dad. He was underneath the tree, and I said, 'Mommy, mommy, daddy ate Santa Claus!' I think that was very traumatic for me. I was a kid so at that point they had to sit me down and say Santa is very busy, and he can’t be everywhere at the same time so dad is taking over and helping him out, and I was like bullsh**!"

Fellow DWTS champion Carson said she still believes in Santa – well, at least she did.

"I think I was about 8 or 9. I was actually devastated. I just loved Santa Claus. I believed in it so much, and my dad was like 'honey, he's not real,'" she said. "It got to the point where people would still make fun of me at school because I still believed in Santa Claus. They're like, 'Sweetie, we have to tell you the truth because you’re getting made fun of at school.' They were like, 'He's not real,' and I was like 'No!'"

The  Young and the Restless actress revealed to ETonline that she knew the truth about Santa at a young age. "I found out that Santa was not real from my parents, and then I told the neighbor's girl that Santa was not real. The neighbor's parents got so mad, and my parents got mad at me for telling her."

Lindner could not be fooled: "I knew for a long time though as a kid even when I’d go see Santa to take pictures with him."
