Beyonce's birthday isn't until Wednesday (September 4), but that didn't stop Queen Bey from kicking off her birthweek (or is it birthmonth?).

The "Spirit" singer joined her husband, Jay Z, at the Made in America music Festival. And although she was there to enjoy some live music as a fan instead of as a performer, her loved ones gave her the sweetest surprise -- a birthday cake complete with full serenade of "Happy Birthday!"

Luckily for us, one fan shared a clip of it on Instagram.

Before she got to blow her candles out, she also caught Lizzo's epic performance. And while one photo of the "Truth Hurts" singer performing shows Bey and Jay enjoying themselves backstage, Lizzo couldn't help but get excited that they came to her set.

"Swipe to lose your f---ing mind 🐝," she posted on Instagram.

Meanwhile, Beyonce recently shared her own moments from the music festival on IG, too. And she's looking fierce as ever.
