(CNN) -- It seems the controversy surrounding TLC's "Toddlers & Tiaras" and its pint-sized stars is never-ending.

After one contestant dressed as Julia Roberts in "Pretty Woman," another, Isabella Barrett, was filmed singing LMFAO's "Sexy and I Know It" at an event.

Barrett's mother, Susanna, has since filed a lawsuit against TMZ, Huffington Post and Daily Mail Online, among other media outlets, for running stories that she alleges "sexualize" her 5-year-old daughter, according to court documents obtained by CNN.

"After this firestorm, I quickly protected my daughter by having cease and desist orders sent to most media outlets that ran the story," Susanna said in a statement provided to CNN, adding, "I intend to clear my daughter's name."

Barrett also detailed her version of the events shown in a video published by TMZ. (In the video, Isabella can be seen singing along to "Sexy and I Know It" at a DJ booth with a microphone in her hand.)

News organizations reported that the Barrett's were at a nightclub, however, Susanna said in her statement that she and her daughter were actually at "a pet friendly charity event at an American bistro restaurant in New York City at 7:19 p.m. It was a private well-lit event with vendor tables and pets in attendance."
