Mariah Carey knows how to throw a Halloween party!

The pop superstar spent the spooky holiday living it up with friends and family at a palatial, Airbnb estate in Beverly Hills, California. Her ex, Nick Cannon, and their two adorable 4-year-old twins, Moroccan and Monroe, were among those in attendance.

For the big night, Carey dressed in all leather as a "glamorous witch" while Cannon donned a green mask and came as The Hulk. Taking after their father, the former couple's kids got in the super hero spirit with Roe rocking a Pink Power Ranger costume, and Roc wearing an awesome Batman suit.

"They wanted to be super heroes," Mariah told ET's Carly Steel, who spoke with the singer during her big Halloween bash. "They've been celebrating Halloween since August. So I figured, you know, we should have something fun, and a haunted house and really be festive so they can enjoy the holidays."

While Carey's boyfriend, billionaire James Packer, also attended the celebration dressed as The Phantom of the Opera, in a black suit and a masquerade mask, the 45-year-old "We Belong Together" singer said that she was glad her 35-year-old ex was at the party to spend time with their children.

"It was cool. It was nice," Carey said, smiling. "It's really good for the kids."
