Mariah Carey and Nick Cannon's twins dressed up as superheroes this Halloween and the proud parents shared the moment with their fans.

The 43-year-old singer uploaded an Instagram photo of Moroccan and Monroe standing on a staircase wearing Superman and Superwoman costumes. The siblings held their hands in the air.

"Have a super happy Halloween," Carey captioned the adorable moment.

Cannon also uploaded several videos of the toddlers as they enjoyed their Halloween. In the first video, the twins repeated the words "Happy Halloween."

In another video, Cannon asked his daughter, "Monroe, where do you live?" The 2-year-old responded "New York City." He then asked Monroe who the president of the United States is. Although she couldn't pronounce the leader's name precisely, she answered accurately with "Barack Obama."

In the last clip, Cannon joined his two children also dressed as Superman. He played with his son, who hit him in the face with a boxing glove. Cannon pretended that the hit knocked him out and Monroe ran to console her father and asked him if he's okay. She later told Cannon, "Be careful daddy."
