The 48-year-old actress, who is known for her comic roles, said Louis does not laugh at her jokes, reported Contactmusic.
"He doesn't find me funny at all! The only time he thinks I'm funny is when I go, 'You know you need to go to bed.' He goes, 'You so funny mamma. You so funny.'
"He knows exactly what he's doing. But he's hilarious. He is hysterical. I'm just here to change diapers and feed him and make money for school. That's my purpose here and it's worth it," she said.
