Taylor Swift had so many stars at her birthday party – including her good friends Camila Cabello and Halsey!

The two singers were spotted heading inside Oscar Wilde restaurant to help Taylor celebrate her birthday on Friday night (December 13) in New York City.

Camila and Halsey both performed at Z100′s Jingle Ball that evening and they left right after their sets so that they could party the night away with Taylor.

A bunch of stars were in attendance at the holiday themed event and Camila even left with a Santa hat on her head!
