Kaitlyn Dever chills out with Peyton List during her Sweet Sixteen Celebration at Big Bear Lake, Calif., last weekend.

The now 16-year-old Last Man Standing actress celebrated with her closest friends and family — including Blake Michael, Sammi Hanratty, Kenton Duty, Keely Marshall, Juliette Angelo, Spencer List, Eric Unger and co-stars Molly Ephraim and Christoph Sanders.

“Road trip, snow, s’mores, christmas cookies, and giant sleepover with friends? …bring it on #sweet16,” Kaitlyn tweeted.
