Reese Witherspoon turned a recent family outing into a cute TikTok moment.

The Oscar winner attended the "Sing 2" premiere in Los Angeles on Dec. 12 and walked the red carpet with her family -- including husband Jim Toth, daughter Ava and sons Deacon and Tennessee -- by her side.

Witherspoon, 45, took to TikTok to post a then-and-now video, set to Simple Plan's "I'm Just a Kid," of the fivesome posing in the same configuration five years apart at the 2016 premiere of "Sing." The video has been seen 3.3 million times at the time of this article being published.

"Buffy the Vampire Slayer" star Sarah Michelle Gellar responded to the clip when it was shared on Instagram, writing, "This is an amazing flashback - they get older you look younger."

Witherspoon shares daughter Ava, 22, and son Deacon, 18, with ex-husband Ryan Phillippe, whom she was married to from 1999 to 2008, and son Tennessee, 9, with Toth, whom she married in 2011.
