Sandra Bullock's son doesn't find her funny.
While the 48-year-old actress is known for her comedic roles, she admitted three-year-old Louis doesn't laugh at her jokes.
She told E! News: ''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.''
While Louis doesn't find Sandra funny, 'The Heat' director Paul Feig thinks she and Melissa McCarthy could be Hollywood's next great comedy duo.
The filmmaker was extremely pleased with the chemistry between the two lead stars of his new female buddy comedy - in which they play rival police officers forced to team together - and thinks they are even funnier than 'Rush Hour' stars Jackie Chan and Chris Tucker, who earned critical acclaim for their own on-screen partnership.
He told BANG Showbiz: ''To me they are 'Rush Hour' times ten.''
