Reese Witherspoon uses Snapchat to talk to her children

Reese Witherspoon uses Snapchat to communicate with her children.

The 40-year-old actress joked that the easiest way to get in touch with her daughter Ava, 17, and son Deacon, 12, is Snapchat because they rarely call her back.

Speaking on the ‘Today’ show, she said: "I have two teenagers, and I’ve discovered that they will Snapchat me back, but they will not call me back. And I think it’s important for people to communicate well with their children."

And Reese also revealed that she relies on Ava for "brutally honest" fashion advice.

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

Along with Ava and Deacon, from her first marriage to Ryan Phillippe, Reese also has a son, Tennessee, four, with her second husband Jim Toth and she admitted that the children poke fun at her for her Southern slang.

Reese explained: "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?’ My little four-year-old will be like, ‘He did done do!’

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