Olivia Rodrigo Feels ‘So Grateful’ After Ringing in 21st Birthday With Giant ‘Guts’ Cake

The Spicy Pisces is officially 21. And after celebrating her milestone birthday Tuesday (Feb. 20) with a huge birthday cake and a party with friends, Olivia Rodrigo shared her gratitude on Instagram. 

‘21!!!” the pop star wrote, sharing a photo in which she poses next to a five-tier “spill ur guts” cake frosted with her signature red and purple colors. “so grateful for all of the incredible things I’ve been able to experience so far and so excited for all the good times ahead💓💓💓”  

Rodrigo also included a video of her getting showered by dozens of balloons falling from the ceiling, as well as a childhood snap in which she stands in an elementary school classroom wearing a handmade “Happy Birthday” hat. She added in her caption, “thx 4 all the love💋” 

The day prior, the “Drivers License” singer marked her “last day of being able to underage drink (hypothetically)” on Instagram, sharing pictures with Tate McRae, The Kid LAROI, Finneas, Madison Hu, Iris Apatow, Conan Gray and more friends at a party. The pre-birthday festivities also featured some b-day cake, this time with funfetti sprinkles and tall candles. 

Fittingly, Rodrigo has since unveiled a limited edition “Spicy Pisces” shot glass for sale on her online merch store. 

The former Disney star’s birthday caps off a pretty spectacular 20th year of life, during which she performed on Saturday Night Live, attended her third Met Gala, picked up six Grammy nominations and released her sophomore LP Guts, which debuted atop the Billboard 200. Just days prior to turning 21, Rodrigo won both song (“Vampire”) and album of the year at the 2024 People’s Choice Awards. 

She is now gearing up to launch her GUTS World Tour, which kicks off Friday (Feb. 23) at the Acrisure Arena in Palm Springs. The trek will mark Rodrigo’s first-ever arena tour and will see the star traveling through North America and Europe before closing out with a four-night run at the Kia Forum in Inglewood, Calif.
