Katy shot a segment for the show -- which was supposed to air on New Year's Eve -- in which she sings a cleaned-up version of her song, "Hot N Cold" with Elmo.

The song made its way to YouTube Monday and racked up nearly a million views. But some parents started complaining her cleavage was too front and center. We've learned producers have decided not to air the song on the show.

Among the parental comments:

-- "You can practically see her t*ts. That's some wonderful children's programming."
-- "they're gonna have to rename it cleavage avenue"
-- "my kid wants milk now"

Fact is ... what looks like Katy's bare chest is actually covered in flesh-colored mesh that goes all the way to her neck.

Lindsay Stripped Down in Secret Fashion Shoot

We're sure there's a reason Lindsay Lohan threw on a ninja mask and flashed some underboob for a secret shoot for Marc Ecko, but it doesn't really matter ... we got the pics, so check 'em out already!

OK, now to the facts -- It was all part of Marc Ecko's secret "Muse" campaign directed by Markus Klinko and Indrani -- a secret he's had to keep under wraps for several months ... hence the mask.

TMZ has learned Lindsay posed for the shoot back in May -- right around the time she was getting into trouble with Judge Marsha Revel.

We're told Marc chose Lindsay because he wanted someone "whom fascinated us -- for better or worse."

Well, mission accomplished.

Melissa Rycroft Peek-a-Boob with the Stars

Melissa Rycroft and partner Tony Dovolani got a perfect score last night on "Dancing with the Stars" -- but was the score for their dance, or Melissa's left breast, which made a surprise appearance towards the end of the routine.

Listen carefully -- after ending the routine by jumping on the judges booth, Melissa gets flustered and clearly says "My boob came out!"

Unfortunately, the camera dude missed the money shot...
