The 45-year-old actress raises sons Sasha, 6, and Samuel, 5, with actor partner Liev Schreiber, reported E!Online.
"My sons? They're very honest. My youngest one particularly has been known to say, 'Ewww, Mommy, I don't like that dress!'," Watts said.
On the day of the Oscars, which will take place this Sunday, the actress is planning to spend her morning with her family.
"I hope I get a good night's sleep the night before. It's not so high pressure for me. So I can just show up and enjoy," she said.
