Britney Spears surprised Kate Hudson this weekend when she crashed her game night gathering.

Sharing a photo of herself with Hudson via Instagram, Britney Spears and Kate Hudson look like sisters with their blonde hair. They were both wearing black tank tops, too, making the resemblance even stronger.

“Two blondes… Too much fun. ? Loved hanging with you last night @katehudson!” Britney Spears captioned the photo.

While it’s uncertain what games were played at Kate Hudson’s game night, one thing is very sure. She was beyond excited when Britney Spears showed up.

Britney Spears is mom to two sons, Sean Preston and Jaden James. Kate Hudson is mom to two sons, too–Bingham Bellamy and Ryder Robinson. Since the kids weren’t at the crashed game night, it’s safe to say the ladies weren’t playing Chutes and Ladders. Maybe some serious Cards Against Humanity was played?

Wouldn’t you love to have been present when Britney Spears crashed Kate Hudson’s game night?
