On Halloween, many celebrities hit the town in their best costumes to celebrate the special day, even Mariah Carey and Nick Cannon spent saturday night together with their adorable children at a family-friendly Halloween party. The party was held at a $15 million estate near Beverly Hills that Carey rented from Airbnb. The party featured a dance floor, candy apple martinis for adults, fried mac and cheese for kids and Sugar Factory candy that was available for all.

Reports from Eonline said that the popstar portrayed as a beautiful 'witch' in a long, low-cut, body-hugging black dress with matching gloves, while Carey's ex-husband Cannon wore a dark green sweatshirt to complement his 'Hulk' mask. Twins, 4, were also dressed for the celebration - Monroe dressed as a 'Batgirl' and Moroccan dressed as 'Batman.'

A source said that Mariah and Nick got along great and were super friendly towards one another. Before visiting neighboring homes, Monroe and Moroccan showed off their 'Batman' and 'Batgirl' outfits, as mommy and daddy posed for family photos. The twins would later receive plenty of candy while trick-or-treating. It was also reported that Cannon spent most of the night twirling Monroe around the dance floor.

Although Carey and Cannon filed for divorce at the end of 2014, they have remained friendly for the sake of their children. Besides this Halloween gathering, the family of four also came together to celebrate Easter earlier in the year.

In fact, Cannon is supportive of Carey's new man. Last summer, a source said that Nick is doing well in his personal life and he just wants the mother of his kids to be happy. As long as his kids are in good hands, he will support any decision Carey makes.
