Michelle Williams' Oscar Day Plans With Daughter Matilda

Exclusive! Get the scoop on Oscar-nominated star's Academy Awards prep routine. Plus, has she picked a dress?

Michelle Williams isn't the only one in her family who's excited for the Academy Awards.

We hear the My Week With Marilyn star's 6-year-old daughter, Matilda, is also getting in on the Oscar fun.

Get ready for some major cuteness...

Williams' BFF Busy Philipps tells us Matilda will be helping her mama prep for the red carpet on Sunday.

"Both of our daughters will be around, that's always a little chaotic," Philipps said at last night's Sir Charlie Chaplin Oscar party at Chateau Marmont in West Hollywood. "The little girls like to see their moms get dressed up and then they don't want us to leave."

The Cougar Town funnylady says Matilda and her daughter, Birdie Leigh, will be having a little party of their own while she and Williams are at the big show.

"Matilda's got all her family with her and my daughter will be with them and my husband," she dished. "So I think they're going to be together. We'll have them have a little playdate. So cute."

So has Williams decided on a dress yet? "She has," Philipps teased. "We both have."

We can't wait to see both of you ladies on the red carpet. Let us know if you need a babysitter.
