Can you imagine what it would be like if Britney Spears [1] showed up to your game night? That's exactly what happened to Kate Hudson [2], who shared the most epic snap of herself hanging out with the pop star on Saturday. "That moment when @britneyspears shows up to your game night and your all like #itsbritneybitch," Kate wrote. Soon after, Britney posted two shots, captioning one, "Two blondes... Too much fun. Loved hanging with you last night @katehudson!" Last week, Kate sparked dating rumors after spending the weekend in Florida with Nick Jonas [3]. While Nick later refused to comment [4] on the rendezvous, we're still deciding how we feel about the whole thing [5]. Read on for more of Kate and Britney's night, then for some Kate-themed Halloween [6] inspiration, check out her star-studded party [7] last year.
