Jennifer Garneris 50 going on 15.

The Golden Globe winner, 50, proved that she’s still hip to the trends as she jumped on the “Teenage Dirtbag” TikTok challenge trend, sharing a series of throwback photos from her teen years in avideoon Thursday.

“My ‘Teenage Dirtbag’ photos,” Garner wrote with a clip of herself standing in front of San Francisco’s Golden Gate Bridge, set to a sped-up version of the 2000 Wheatus song.

The video then cycled through some hilarious retro photos of Garner practicing the saxophone, doing ballet and playing Dorothy in a staged production ofThe Wizard of Oz, among other fond adolescent memories.

Garner, whocelebrated her 50th birthdayin April, previously said she"can’t wait" to celebratethe milestone birthday with her family.

“I turn 50… yeah, Easter Sunday,” she toldExtraearlier that month. “My family has tickets to come out. My parents and my sisters, nieces, and nephews. I don’t know what we’ll do, but I can’t wait. We’re gonna have a good time.”

Mark Ruffalo, who starred with Garner in13 Going on 30andThe Adam Project, added: “I would never guess Jen is 50.”

“Eventually you’ll start to be like, ‘Oh, I’m aging. It’s all going to go to hell in a handbasket.’ That is when you want to start with a little bit of retinol, just a little something,” Garner explained in November.
