Haters gonna hate: after ringing in her 25th year while on stage performing at Z100's Jingle Ball, Taylor Swift celebrated her birthday last night with a lowkey pizza party in her Tribeca home. Or as lowkey as you can get when your party's attended by Justin Timberlake (who seems to be wearing a hat shaped like the poo emoji), Sam Smith, HAIM, Karlie Kloss, Chrissy Teigen, Nick Jonas, and oh, no big deal, Jay Z and Beyoncé. Earlier in the day, Taylor received Billboard's Women In Music event, where she was honored with the Woman of the Year award and serenaded "Happy Birthday" by none other than Aretha Franklin (watch the video below). And in typical Taylor fashion, she accepted her award with a self-consciously bad joke: "I turn 25 at midnight tonight, and I fully intend on partying like it's 1989. I knew it would be a bad joke when I wrote it, but I did it anyway." Tay and Bey chatted at the event (see the photo below); maybe that's when Taylor invited her to the party?
