Jason Momoa was a guest on her daytime talk show and she thought it would be fun to invite Remington and River on set to ask him questions.
Three-year-old Remington was clearly lost for words as he realised he really was in the presence of Aquaman, but River was bolder and asked Momoa if he knew "The Little Mermaid", prompting Jason to respond, "Ariel? Yes, Ariel's very sweet. She's very nice."
River then asked, "Where does Aquaman go to the bathroom?" and Jason fired back, "Everywhere."
The interview aired on Wednesday, November 13.
