No Post-Birth Beer for Mariah Carey

After giving birth to not just one baby but two, you might excuse a new mom for wanting a drink... but singer Mariah Carey is quashing earlier reports that she had a beer after her twins Moroccan and Monroe were born last spring at a Los Angeles hospital.

The beer allegation prompted the involvement of California Child Protective Services, who, Carey said, investigated whether the babies were subject to "neglect."

"It just doesn't make any sense," Carey told Barbara Walters in an exclusive interview airing on "20/20″ Friday.

Carey said that, at the time, the newborns — who are now six months old — were being cared for in the hospital's neo-natal intensive care unit.

"The babies were in the most protective environment because it's the NICU," she said.

Carey said the beer story started with a suggestion by a nurse who brought the singer a beer, saying it would help improve lactation.

But, Carey said, "I didn't even drink the beer."


Double Vision of Love

Nearly six months after their birth, Moroccan and Monroe -- Mariah Carey and Nick Cannon's twin son and daughter -- are ready for their primetime debut.

Mariah and hubby Nick introduced their bundles of joy to Barbara Walters during an intimate visit to their lavish NYC apartment for a 20/20 interview airing this Friday, October 21 at 10pm on ABC.

In a just-released new shot from ABC, Walters bonds with the sweet little boy and girl, born April 30, held by their beaming parents.

Justin Bieber Marvels at Mariah Carey Christmas Collab

As Justin Bieber told MTV News during the live stream that followed the premiere of his "Mistletoe" video, the Busta collaboration is one he'll always remember ... mostly because he considers it to be quite brilliant.

"If you really think about it, it's genius, because it's rapping on a Christmas album ... and, like, I'm rapping on it. And then it's singing," he explained. "It's cool. [Busta's] got, like, a percussive voice to him [and] the beat was so crazy. I'm actually playing drums on that song, playing the snare."

And then, of course, there's his collabo with none other than Mariah Carey, on a version of her instant-classic "All I Want for Christmas Is You." If you thought he was blown away by his Busta team-up, well, you haven't heard anything yet. And he owes it all to none other than Randy Jackson.

"Mariah Carey is doing it with me! It's incredible. So excited," he said of "All I Want." "We wanted Mariah from the beginning, but we kind of thought it was really hard, so we didn't really push the idea. But she's on my label, so we reached out to some people, she got in contact with us, and Randy Jackson was actually at the studio with us, and I was like, 'Yo, you think you can help get Mariah on the Christmas album?' And he was like, 'I'm actually going to see her in New York on Monday,' and I was like 'Yo, go do that!'"
