Reese Witherspoon knows that the only way to get her message through to her kids is if she talks to them using a social media app. As a matter of fact, the Hollywood mom did just that when her kids told her that they needed their back to school supplies at the very last minute. Witherspoon decided to take to her Snapchat account to express just how surprised she was to find out about it the day before school.

According to People Magazine, Witherspoon decided to snap her surprise upon hearing that her kids aren’t prepared to go to school yet. Adding a few funny filters, the Hollywood mom captioned her post with, “Are you seriously telling me TODAY about all the school supplied you need TOMORROW?” The actress has three children: Ava, 19, and Deacon, 15, who she shares with her ex-husband Ryan Phillippe, and 6-year-old Tennessee who she shares with her current husband, Jim Toth.

Witherspoon didn’t reveal who told her they needed to buy all of their pens, pencils, notebooks, backpacks and lunchboxes at the last minute, but the actress did say that she often uses creative ways to communicate with her children. If she can’t come across clear enough to them directly, then she does so using social media.

The celebrity mom once told the publication that her daughter Ava pointed out that while she and her brother look like their father, they definitely got their “weirdness" from their mother. She said, “I’m goofy. I send them weird Snapchats of me doing old man voices and goofy teeth. That’s the way we communicate.”

If that weren’t enough, Witherspoon also says that she often likes to send her children random photos throughout the day. While there’s no doubt that she does keep up with them to see where they are or what they are doing, she also can’t help but let that goofiness side of her’s show, too. Apparently, her middle child is the one who gets the most phone notifcations from his mom.

“I like to haunt [Deacon] during the day, so I’ll send him pictures of disgusting animals and be like, ‘I’m feeling like this today,’ ” she said, giving blobfish and massive snails as examples. “And I’ll put #mondayfeels’ or something like that … I just try to gross him out.”

But when she’s not sending her kids goofy texts, she is dedicating sweet messages to them on her Instagram account. She often likes to share their accomplishments and express just how proud she is of them.
