Both single moms documented their hang session on Instagram, inspiring some new squad goals.
"That moment when @britneyspears shows up to your game night and your all like 👀💃🎉#itsbritneyb----," Kate, 36, wrote alongside one photo with her new pal.
Britney, 33, also also shared a few snapshots with her new movie-star buddy, including one she captioned, "Two blondes... Too much fun. 👯 Loved hanging with you last night@katehudson! ❤️"
