Reese Witherspoon on Getting Advice From Her Look-Alike Daughter: 'I Depend on Her Brutal Honesty'

Plus, hear the hilarious way the Oscar winner communicates with all her kids.

Reese Witherspoon may be the brains behind her new lifestyle fashion brand, Draper James, but she admits she still relies on style advice from her family and friends.

During a sit-down interview with NBC's Today show, the Oscar winner revealed her 17-year-old daughter, Ava, gives her the thumbs up (or thumbs down!) on her daily outfit choices.

"I usually ask my daughter, my 17-year-old daughter, 'Does this look good?' and she'll be honest with me," the 40-year-old actress explained. "She'll be like, 'No. You do not look good. You cannot wear that.' So I depend on her brutal honesty."

Reese, who is also mom to Tennessee, 4, and Deacon, 12, joked that it's sometimes hard to communicate with her kids, unless it's over social media.

"I have two teenagers, and I've discovered that they will Snapchat me back, but they will not call me back," she dished. "And I think it's important for people to communicate well with their children."

The New Orleans native also revealed that her children often poke fun at her for her quirky Southern slang.

"I'll say, 'He did do, but he didn't done do. He done did that.' They're like, 'What? Why you talkin' did done?'" Reese said. "My little 4-year-old will be like, 'He did done do!'"

"They think it's hysterical, but they don't understand what I'm saying," she added. "I don't always know what I'm saying, but sometimes people do."

Reese pointed out that the reason she gave Draper James a Southern twist was to "celebrate the traditions and the people who raised me and gave me so much of who I am."

"If you never try, you'll never know," she said of becoming an entrepreneur. "I'm always putting myself out there and always say to the kids, 'You know, sometimes you just have to jump two feet into a cold pool.' Maybe it's going to pay off, maybe it's not, but at least you took the chance."
