Those in glass houses shouldn't throw stones ... especially when that house is an abortion clinic ... so says a "Toddlers & Tiaras" mom who's PISSED Vanessa Williams went off about pageant parents in a recent interview.

FYI -- Williams recently appeared on "Anderson" and when asked about the child pageant world said, "When the child is screaming and saying, ‘I don’t want to do this. I don’t feel like doing it.’ When they are using special juice to get them hyped ... that’s not my world and I would never have my kids do that.”

The comments didn't fly with "Tiaras" star  Wendy Dickey -- aka Paisley's mom -- who says she was personally offended ... and lashed back:

"Posing nude and having an abortion is 'not my world' and I would never have my kids do that ... so easy on the judging Vanessa!"

Dickey is clearly referring to the revelations Williams makes in her new book -- in which she admits she got an abortion in high school ... and explains how she appeared in Penthouse.

We reached out to Williams ... but so far, no response.

The mother of 5-year-old "Toddlers & Tiaras" star Isabella Barrett doesn't care that her daughter's performing LMFAO's "Sexy and I Know It" in nightclubs -- telling TMZ, "That's a real catchy song!"

Susanna Barrett was out shopping with her daughter yesterday in NYC -- telling us, Isabella's a big fan of top 40 music ... and that's why she was able to spout off the LMFAO lyrics at a New York nightclub this week. According to Susanna, Isabella also loves Lady Gaga and Rihanna.

But Susanna quickly pointed out ... there are limits -- for instance, Isabella has never seen the music video for "Sexy and I Know It" ... which shows the lead singer shaking his man-package around in a Speedo (below).



All in all, Susanna insists the nightclub experience was pretty tame -- "We went for a pet charity event ... We left by 9 o'clock."

She's just 5 years old, but "Toddlers & Tiaras" star Isabella Barrett is already making nightclub appearances -- singing songs about her sex appeal -- and TMZ has obtained video evidence.

Barrett graced Libation NYC with her presence Monday night for a special charity fundraising event -- where she danced and sang along to LMFAO's "Sexy and I Know It."

In case you forgot -- Isabella is the same girl who said her fellow "Toddlers" star Paisley Dickey dresses like "a hooker."

Sure, the video's pretty cute -- but when we were six ... we sang songs from "Barney & Friends."

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."

You don't say!

Humanity reached a new low last night ... when a 5-year-old "Toddlers & Tiaras" star TRASHED a rival 3-year-old beauty queen ... saying she DRESSES LIKE A HOOKER ... seriously.

5-year-old Isabella Barrett was leaving a spray tanning sesh in NYC -- again, she's 5 -- when she went off on 3-year-old Paisley Dickey for allegedly copying her spray tan ways.

Barrett (presumably with her mother's coaching) told TMZ ... "Last time I was here, Paisley was trying to copy me ... but MY mom doesn't dress me up as a hooker."

Barrett (and her mother) are referring to the infamous "Toddlers" episode ... when Paisley dressed up like Julia Roberts as a prostitute in "Pretty Woman" for a beauty pageant (below).


But Barrett's insult raises some questions -- namely, how the hell does a 5-year-old know the word "hooker"? 

Based on how Isabella looks to her mother for approval throughout the video, you'd think her mom coached her to say it ... but that's ridiculous, right?

What mother in her right mind would teach her 5-year-old daughter ... to say another little girl dresses like a sex worker? Good thing these people have standards. 

The show "Toddlers & Tiaras" is often criticized for sexualizing young children -- but what you see on TV is nothing compared to what happens when their moms get together for a party.

TMZ has obtained a video of two of the mothers featured on the season premiere of the show ... dirty dancing with a guy during a viewing party attended by several of the moms.

In the video, Lauren (who hosted the party) can be seen straddling a guy named Blake Woodruff, a talent manager who is also featured on the show. Then Blake hops on the back of Crystal and proceeds to ride her, while Lauren dances on a chair behind them.

We're told the dancing all came about when the moms were talking about the criticism the show gets and how it is oversexualized.

What is particularly ironic ... Crystal was featured on the show teaching her daughter Anna Maria how to "booty bounce" (see below).



Clearly the apple does not fall far from the tree.

The mother of "Toddlers and Tiaras" star Paisley Dickey has done it again ... dressing up her 3-year-old daughter in a questionable outfit -- this time a motorcycle biker chick Halloween costume.

While Paige's mom thankfully left the baby hooker "Pretty Woman" getup at home this time, she did deck out her baby girl in a very adult little black mini dress and motorcycle boots.

So, we gotta ask ...   

The mother of the 3-year-old girl dressed as a prostitute on "Toddlers and Tiaras" tells TMZ, she's a good mom -- and insists "no harm was done to my child" by dressing her as a hooker.

Wendy Dickey tells us, her kid had no idea what she was dressed as anyway -- and the costume was "less revealing than gymnastics wear and swimsuits."

According to Wendy, the hooker outfit (below left) -- based on Julia Roberts' character from "Pretty Woman" -- "is a lot less harmful."

Wendy says she dressed her daughter as the "classy" Julia Roberts from the end of the movie as well (below right) -- but TLC edited that part out.


Wendy says, "I'm raising my child just as well as any mother does ... I take my kid to church every week ... at least I'm not forcing them into sports and getting my child injured like some parents."

Wendy adds, "People need to look at their own family and what they're doing. I don't know why people are focusing so much on pageant moms when there's much more harmful things people are letting their children do!"

A powerful parents group is BLASTING the people behind the TLC reality show "Toddlers and Tiaras" -- after a parent dressed a 3-year-old girl as a prostitute for a beauty pageant.

The show has been under fire over a promo spot, featuring a pint-size beauty queen dressed up like Julia Roberts in "Pretty Woman" -- during her street-walking hooker phase.

But the Parents Television Council is LIVID -- claiming, "We have a serious problem when a network formerly known as The Learning Channel features a toddler, who probably hasn't even learned to read, dressed as a prostitute showing off her sexy strut."



The PTC adds, "There's no question, TV executives are complicit in robbing these small kids of their childhood."

"For years we've seen adult sexuality being inappropriately and aggressively foisted on innocent young children, but children today are being sexualized at younger and younger ages. All available data suggests they will suffer for it later in life."
