ET was exclusively with Marie Osmond as the star revealed her very own fashion doll!

Surrounded by fans, Marie unveiled the Rock This Town Marie fashion doll at the Flamingo Hotel in Las Vegas.

"The last time I was a fashion doll I was about 15 or 16 or something like that, and it was really my daughter's idea --she's 20, Rachel -- to come out with a new Marie fashion doll," Marie tells ET. "And so, she's dressed in the dance outfit I wear at the end of our show here at the Flamingo, and so we're unveiling her tonight."
