'Toddlers & Tiaras' Mother Lashes Out Over 'Hooker' Insult -- Blame the Mom, Not the Girl

The mother of "Toddlers & Tiaras" star Paisley Dickey is firing back after 5-year-old Isabella Barrett accused her daughter of dressing like a "hooker" -- claiming Isabella's mom is to blame for filling the girl's head with garbage.

Wendy Dickey tells TMZ, "No blame is to this sweet little girl [Isabella], not her fault. She's just listening to her mom!"

Wendy's referring to a video TMZ posted this afternoon, in which a freshly spray-tanned Isabella (right) says, "Last time I was here, Paisley was trying to copy me ... but MY mom doesn't dress me up as a hooker" ... a jab at Paisley's recent "Pretty Woman" costume (left).

But Wendy's unfazed -- telling us, "I am used to this kind of behavior now from jealous moms. Doesn't even bother me anymore ... This is Isabella's mom's way of trying to get attention for her daughter."
