Peyton List Participates in Biggest Water Fight Ever at JJ's Summer Bash 2015!

Peyton List rocks her swimsuit under a cover-up as she hits up the 2015 Just Jared Summer Bash presented by SweeTARTS Chewy Sours on Saturday (July 18) at a private residence in Los Angeles.

The 17-year-old Bunk’d star was joined by her brother Spencer, as well as fellow sibling duos Joey and Hunter King, and Sophie and Nick Simmons.

Naomi and Ely’s No Kiss List star Pierson Fode, Jessie‘s Chris Galya, Vine stars Jake and Logan Paul, and Peyton‘s Bunk’d co-star Maddie May were also in attendance.

During the bash, Peyton and Spencer went to battle epic with the Nerf Rebelle Soakers before a ton of more stars joined in for a big water fight!

FYI: Peyton is wearing a LoveShackFancy romper.
