The Elusive Chanteuse strikes again! Mariah Carey hosted a Halloween party in Beverly Hills this past Saturday, Oct. 31, that was attended by both her ex-husband Nick Cannon and her current boyfriend, James Packer.

The kid-friendly bash, which took place at a private $15 million Airbnb rental mansion, included cute activities like dancing and bobbing for apples. For the spooky holiday, the Grammy winner dressed as a sexy witch, while her two 4-year-old twins — affectionately known as "dem babies" — disguised as superheroes. Monroe looked adorable in an electric pink getup as Batgirl, while her twin brother, Moroccan, made his toughest face as Batman.

"A #ghoulicious time with dem babies #halloween," Carey captioned the snap on her Facebook page.

Photos from inside the party showed Cannon, dressed as the Incredible Hulk, playing with their two kids. One snap featured both parents hanging out with their little ones on a golf cart. An observer tells Us that Cannon, 35, was also spotted at one point on the dance floor, where he twirled his daughter around.

Once the party was in full swing, Carey's billionaire boyfriend Packer arrived in a full suit and Phantom of the Opera-inspired black mask. Another eyewitness tells Us that he walked over to Carey to give her a kiss on the lips.

"They were affectionate all night," the eyewitness tells Us of Packer and Carey. "We saw them kissing and borderline making-out multiple times at the party. Clearly he's comfortable with her kids . . . though I didn't see James interact much with Roc and Roe at all."

The same observer tells Us that Cannon's whereabouts were unknown once Packer arrived.

Us Weekly broke the news in August 2014 that Carey and Cannon were living apart, and the once totally-in-love couple filed for divorce this past January after six years of marriage. Carey stepped out with Packer in June.

For the sake of their children, both Carey and Cannon have presented a united front and attempted to keep their relationship amicable.

"They love Mommy, they love Daddy," Cannon told Meredith Vieira in October 2014. "We've always been people who are kinda on the go, coming and going, so their life hasn't changed one bit. We spend holidays together, we do everything that we're supposed to do together."
