TAYLOR SWIFT came to PETE DAVIDSON’s work last weekend when she was the musical guest on “Saturday Night Live”.

Not only did she perform her own song, but she also appeared with Pete in a pre-recorded sketch where they sang a song called “Three Sad Virgins“.

The thing is, Pete’s been seeing KIM KARDASHIAN, and last we heard, Kim and Taylor were mortal enemies. So how did that work?

Sources say Pete was a total pro. “He is clearly aware of the history that Taylor has with Kim and Kanye, and he was not going to make it a thing. He wasn’t going to treat her differently.

“To cause any drama is the last thing he had any plans to do, and that is why it was important to make friends with Taylor and do a skit with her.”

Grown ups acting like grown ups. Wild.
