In December, Witherspoon told ET that she's not exactly the cool mom, admitting that her kids get embarrassed when she sings Drake songs, but are impressed with her social media skills. "Well, at least I know how to work Snapchat," she quipped. "I think, you know, most moms don't. [My kids] are like, 'You actually know what Snapchat is and you're actually sending us a lot of Snapchats.' So, maybe that's kind of a cool thing."
