The Gifted co-stars appeared on The Ellen DeGeneres Show to promote the upcoming film and discuss their on-sent swear jar as well as Grace's adoration of Ellen and Evans' tap dancing skills.
"You still have to pay me for the swear jar," Grace told Evans after he joked he paid her to give him compliments.
The Captain America actor and his young co-star then explained to DeGeneres he was forced to pay $5 for every swear and $10 for every use of the "F-word" on set, which Grace then donated to charity.
"Although I kept like $5," Grace joked.
The 11-year-old actress began the interview showing off her stuffed animal "DD" before she and DeGeneres shared their mutual admiration fore each other.
"I watch your show all the time," Grace said. "And it's so exciting to be here because you're my role model and I look up to you."
After the touching moment, Evans paid off one of his debts to Grace by briefly showing off his tap dancing abilities for DeGeneres and the audience.
