(KMOV) -- A St. Louis County mom is still talking about her Christmas Day surprise.

The Bratz Baby Singing Karaoke Doll

She claims a popular singing doll, which she got for her two young daughters, has a dirty mouth. 

The Bratz Baby Karaoke Doll was the big gift for Dawn Hamberg's two daughters.

What she didn't expect was what came out of that doll’s mouth on Christmas morning.

Dawn's daughter claimed that her doll was singing a four-letter profanity.

News 4 listened too, and it was so close that we had to bleep out the words in our reports.

Dawn is not alone. A father in Florida is also shocked and complaining about the same word in the same dolls, which sells for about $50 and is recommended for children 4 years and up.

Dawn Hamberg is also upset and has taken the dolls away from her daughters.

News 4 did try to contact MGA Entertainment, the company that makes the Bratz dolls, to get a comment and even find out if another word was intended in the song lyrics, but we have not received a response.
