NICKI MINAJ EXPLAINS MARIAH FEUD, PUTS BARBARA WALTERS ON BLAST: NICKI MINAJ opened up about her recent on-set fight with MARIAH CAREY during the second installment of her three part E! reality show "Nicki Minaj: The Truth" on Sunday night.


Talking about the videotaped argument that took place in early October during an "American Idol" audition in North Carolina, Nicki explained that “twenty minutes before that happened she egged me on." Nicki said she left the stage because she, quote, doesn't "do well with that passive aggress sh--." But, "when I came back it was another jab." And that's when she got all up in Mariah's grill, as we saw in the video.

“I had to make it clear that if you do this again, I'm going to do this again,” she added. Nicki also revealed that Carey “admitted she did not want another female doing the show. She didn't want someone stealing her shine.”


As for the comments BARBARA WALTERS made on "The View" regarding the incident ... Nicki confessed she was furious that Walters took Mariah’s side without ever asking for her comment. “Am I not good enough for you to get my side because I’m a little black girl that raps?” asked Nicki. “If I was J.Lo you would have called."

EFFIN' WITH THE STARS: Over the years, we've known about a hook up or two on the set of "Dancing With the Stars", but who knew there was this much sex going on!The "National Enquirer" claims A LOT of down there parts are being shared behind-the-scenes and they're blowing the lid off of it.


A "production source" tells the tab, quote, "The number of affairs has gotten way out of hand. There's been so much casual sex behind the scenes that you'd think it's a swingers club, not a dance show."


Okay, here's some of the alleged hook-ups, according to the Enquirer ... Derek Hough has gotten all smoove up in Shannon Elizabeth and Maria Menounos. His sister, Julianne Hough, is said to have knocked boots with Helio Castroneves and Chuck Wicks. Mark Ballas has made the beast with two backs with Shawn Johnson and Sabrina Bryan.


Now we knew about Maksim Chmerkovskiy and Karina Smirnoff because they were once engaged, but the "Enquirer" claims Maks has also gotten some nookie from Willa Ford, Erin Andrews and Peta Murgatroyd. And Cheryl Burke supposedly, allegedly bumped uglies with Chad Ochocinco, Drew Lachey and Rob Kardashian. Bow-chika-bow-wow!

Meanwhile ... Derek returned to "Dancing" last night after missing last week with a serious neck injury. In a post on his website, Derek says his doctors have cleared him to finish out the season, but eventually, he's going to need neck surgery. He told "Extra" he's suffering from a herniated disc and two bones spurs.
