The singer threw a star-studded LA bash for her pregnant best friend just hours after performing a sold-out gig in Philadelphia.
King wrote on Instagram: "Taylor Swift is not only going to be an exquisite godmother, but one of the best friends I could ask for. Thank you for throwing me such an insanely beautiful baby shower. Less than 12 hours after performing for 100k strong."
Some of the names on the guest list included Jessica Alba, Selma Blair, Emma Roberts, Gigi Hadid and HAIM, who took to Instagram to share photos from what looks like the best baby shower EVER.
Swift announced she was going to be the godmother of King's baby in a sweet Instagram post back in March.
