Mariah Carey Has a Spooky Reunion With Ex-Husband Nick Cannon

Holiday parties sure bring out the best in people — just ask Mariah Carey. On Saturday, Mariah dressed up as a sexy witch and hosted her own Halloween bash in LA, which included two very special guests: her boyfriend, James Packer, who dressed up as the phantom from The Phantom of the Opera, and her ex-husband Nick Cannon, who wore all green and channeled the Hulk. Along with James and Nick were her two adorable twins, Monroe and Moroccan Cannon, who donned Batgirl and Batman costumes. That same day, Nick took to Instagram and shared two photos of his children, writing, "#RocandRoe going hard this Halloween! #BatGirl #Batman," with one of the snaps.

Nick and Mariah were married for six years before splitting last Summer, but the two still continue to spend time together for the sake of their children. Earlier this year, the pair reunited for an Easter celebration with their kids, and on Mother's Day, Nick proved that he had nothing but love for Mariah when he gave her a sweet shout-out on social media. Mariah has been dating billionaire James since June. Keep reading to see more photos from the brood's night out, then check out the best celebrity family Halloween costumes.
