Move over, Ryan Reynolds, there's a new Deadpool in town.

In a Sunday Instagram post, Mariah Carey shared a hilarious moment with her twins, Monroe and Moroccan (Rocky), "Deadpool" star Ryan Reynolds and his wife, Blake Lively.

In the photo, Carey, 49, and her eight-year-olds smile alongside Reynolds 43, and Lively, 32. Instead of smiling like his mother, however, Rocky donned a Deadpool mask and crossed his arms.
