"I see something behind those eyes that I'm a little nervous about."
On this Sunday's episode of Mariah's World, Stella's new tour assistant Molly is trying to get settled into her job, but it hasn't been going smoothly.
In this exclusive clip from the episode, Mariah Carey's makeup artist Kristofer meets with Molly to try to get to know her and help her adjust.
"When I'm nervous I'm calm, when I'm very nervous I'm calm and I will go 24 hours without even running to the BR to go pee for the first time in the day," Molly says.
Kristofer then realizes that BR means bathroom, "I'm like BR...?"
"Because I don't want to say, 'Going to the bathroom,'" Molly explains. "No I never say that!"
After having the conversation with Molly, Kristofer reveals what he really thinks about her.
"I guess if I had to describe what I think of Molly is…psychotic…potentially," Kristofer admits.
Take a look at the Mariah's World video above to find out why Molly makes Kristofer "a little nervous."
