The blonde besties showed off their newly formed friendship on social media, where Kate revealed that Britney dropped in on her games night!
Taking to her Instagram page, Kate, 36, posted a cute pic of herself and Britney with their arms around each other (with a healthy dose of photobombing by friends, of course!).
โThat moment when @britneyspears shows up to your game night and your [sic] all like #itsbritneybitch,โ Kate penned.

But the popstar didnโt let Kate have all fun!
Brit, 33, posted two sweet snaps of Kate and herself on her Instagram last night, captioned, โTwo blondesโฆ Too much fun. Loved hanging with you last night @katehudson! โคโ

Dressed in a black tank, the singer looked chic next to her actress BFF, who was sporting a flat-brimmed hat with a metallic detail and a black racer-back.
Even though these two donโt usually hang out together, we can see why theyโd click โ they have so much in common!
The famous friends both have young sons, with Brit being mum to Jayden James, nine, and Sean Preston, 10, and Kate being mum to Bingham, 4, and Ryder, 11.
The budding besties are also recently single! Brit split from her boyfriend of eight months, Charlie Ebersol, in June, while Kate has been flirting with 23-year-old singer Nick Jonas after her break-up with fiancรฉ Matt Bellamy last December.
We canโt wait to see what this dynamic duo does next!

Beautiful besties: The stunning stars looked thrilled to be in each otherโs company.
