Party at Taylor's!
We can only imagine the shenanigans taking place! Pillow fights? Twister? Sewing circle???
All three of them looked cute, especially Karlie, who showed off her supermodel body in an off-shoulder crop top and slit maxi skirt.
Unlike Taylor, she's cool with exposing her belly button!
Gigi's all-black outfit and super tight pants also happened to look like something her video character would totally wear!
In non-fashion news, Lena was joined by boyfriend Jack Antonoff, and Swifty's new squeeze Calvin Harris was there, too.
They can double-date now! Finally!!!
Would YOU want an invite to Swifty's abode? Because we totally would.
