Reese Witherspoonisn’t a regular mom, she’s a cool mom!

Though Witherspoon, 43, is asocial media pro, even she needed a little help mastering one of the newest platforms. Turning to her eldest son Deacon, who will be 16 next month, the mom of three found herself asking the common question: “What is TikTok?”

“Deacon, this is very important. I’ve brought you here because I have questions for you,” Witherspoon told her son in ahilarious social media post, as Deacon playfully muttered, “Oh God.”

Giving a brief explanation of the app, Deacon described it as a “short-form video platform” where people upload clips of themselves lip-syncing or moving around to popular songs.

“Should I be on TikTok?” Witherspoon asked. Even though her son didn’t seem quite as enthusiastic as she did, she tasked him with helping her make her very first post.

First, Witherspoon bust out some of her best moves — but her son didn’t seem impressed. “Like that?” she asked her son.

“No, not like that,” he replied.

As the Oscar winner kept getting progressively sillier with her dancing, her son continued to applaud her skill level. “You look pretty cool,” he said with a laugh.

“@deaconphillippe tries to teach me how to Tik Tok,” Witherspoon captioned the video, adding a crying with laughter emoji. “I think I nailed it…”

Of course, sometimes Witherspoon is the one teaching her son new things.

During an appearance on TheEllen DeGeneresShow this week, theBig Little Liesstar opened up about her experience teaching Deacon how to drive.

“You’re teaching him how to drive?” DeGeneres asked Witherspoon.

“Yes, he’s starting to drive, God help us all,” Witherspoon first joked. “But he’s a good driver, he’s actually a better driver than I am. I get distracted a lot because I see cute dogs and I’m like ‘Oh, I gotta pull over!’ and I literally will pull over the car and get out of the car — if it’s a bulldog,” she admitted, adding, “Only a bulldog. I’m very preferential of certain breeds.”
