During her recent appearance on Watch What Happens Live! with Andy Cohen, Mariah Carey makes it very clear that her feud with Eminem is still going strong, and reveals the real reason why she won't have any more children.

The "Art of Letting Go" singer and the Detroit rapper reportedly dated briefly back in 2001 after they met to discuss a possible collaboration on Carey's album, "Charmbracelet." However, things quickly went downhill from there.

As evident in his 2002 album The Eminem Show, Slim Shady disses Carey in the track "Superman": "What you trying be? My new wife? / What, you Mariah? Fly through twice."

Mariah Carey's revengeful response to the MMLP2 rapper was her 2009 hit "Obsessed," which inspired a video that featured Carey in male drag as Eminem.

Now, years after public fight began between the pair, it was evident that Carey still had sour feelings towards the "Berzerk" rapper. When the WWHL host brought up the topic to the diva during a round of "Plead the Fifth," asking her to say three nice things about Eminem, the "All I Want For Christmas Is You" singer's response was rather sarcastic -- she refused to compliment her long-time enemy, preferring instead to talk about the other type of M&Ms.

"They come in a package that you can carry wherever you go," she sniped. "People love them around the world, and they're tasty. You can have peanut or the regular kind."

"Oh my god, I love it!" Cohen shouted.

In addition, the mother of 2-year-old twins Moroccan and Monroe was asked by a fan caller whether or not she and her husband Nick Cannon were planning to expand their brood.

"If Nick could have the babies himself, then maybe. Then, bring 'em on. We love kids!" she joked. "Here's the thing: This is real. I'm responsible for the kids for like forever. I look at it like, they didn't ask for this lifestyle but here they are."

She then opened up about why she is done having kids: she had a difficult pregnancy when she carried the twins.

"I had pre-eclampsia; I had gestational diabetes," said Mariah Carey. "[It was] a really difficult pregnancy and I was alone most of the time... We love Nick, but he was working! He's the hardest working man in show business."
