Mother Says She Was Assaulted at Disney Channel Taping

The woman behind the suit is Kellie Rodriguez ... who claims she took her kids, her sister-in-law and 3 nieces to a taping in L.A. on December 22, 2011 ... when she noticed she was being checked out by the comedian in charge of entertaining the audience, Ron Pearson.

According to the suit, Kellie was later chosen to participate in an audience competition -- in which the contestants would perform a "silly dance" to the Village People's YMCA ... and the winner would get a prize.

Kellie claims she began to dance ... when "all of a sudden and without warning, Pearson started spanking [her] buttocks with his hands."

In the suit, Kellie continues, "The unwarranted and unconsented spanking was RELENTLESS and did not cease until [Kellie] physically turned around to stop it."

The worst part -- Kellie claims she didn't even win the dance contest.

But there's more ... Kellie claims after the competition, Pearson asked for a kiss on the cheek ... but when she went in for the peck, he turned his head at the last second and kissed her on the mouth instead.

In the suit, filed in L.A. County Superior Court, Kellie claims it was not only unwarranted and humiliating -- but she claims her children were sad and confused ... later asking their mommy, "Why did that man kiss you?"

Kellie wants Pearson to pay ... same with Disney, claiming the Mouse House "condoned, encouraged or ratified" the comic's behavior by employing him in the first place.
