"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.
"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."
