A six-year-old Arizona boy has achieved Internet fame after a video of him reacting to news he’ll have a new little sister went viral.
The video shows Gunner Mertlich, along with his sisters Paisley and Harper, preparing to cut into a cake that will reveal the gender of their newest family member.
“I think it’s a boy,” Gunner tells his father Jason.
But the cheery tone of the video takes a dramatic turn as soon as Gunner slices the cake to reveal a bright pink center. The boy bursts into tears, crying, “I knew it was a girl!”
Jason asks Harper and Paisley if they’re happy with the news, and both girls are pleased. When he asks Gunner, the answer is quite different.
