Bestie night in!

Gigi Hadid and Taylor Swift couldn't help but sing along as they spent the night on the couch watching Grease Live together, and the supermodel's Snapchat story makes us seriously wish we were part of their squad!

"We're also performing Grease Live in the living room," Yolanda Foster's daughter captioned the moment on social media.

The two belt out "Hopelessly Devoted To You" in the clip, and considering they know every word, it seems they are big fans of the classic musical! We wonder what they thought about their mutual ex Joe Jonas' performance? The boybander played with his band DNCE at Rydell High's school dance in one of the scenes.

T-Swizzle should have auditioned for a part!
