Not only did the legendary Aretha Franklin sing Happy Birthday to Taylor Swift on Friday, the singer later celebrated with a whole bunch of A-listers.

Swift, who turned 25 on Saturday, shared a photo on Instagram while celebrating with supermodel Karlie Kloss, Jay Z, Beyonce, Sam Smith, the sisters of Haim and Justin Timberlake, who for some reason was wearing a doo doo mask.

“So this is being 25..... #WHAT #bestbirthdayEVER,” Swift, who headlined Z100's Jingle Ball on Friday, wrote as the caption.

But, they weren't even the only ones who showed up for the festivities. See more photos below.

Swift also showed off her birthday gift from actress Lena Dunham - a cat pendant.

It's kind of hard not to be jealous, right?
