Oscar winner Lady Gaga—who turns 33 today, March 28th—has built an incredible career since releasing her debut single “Just Dance” all the way back in 2008. Since then, she’s collected numerous Grammys, two Golden Globes, and, most recently, an Oscar. She’s also made a point of building a platform based on kindness and acceptance, which is a message everyone can get behind. So, in honor of Lady Gaga’s birthday, we’re sharing some of Mother Monster’s most inspirational moments throughout the years. One warning: You might want to grab the tissues for this one.

When she launched her Born This Way Foundation.

Alongside her mother, Cynthia Germanotta, Lady Gaga founded her Born This Way Foundation, an organization “committed to supporting the wellness of young people and empowering them to create a kinder and braver world,” per the foundation’s website.

Mother Monster performed a legendary set at the 2017 Super Bowl, delivering a subtly political concert that included her hit song “Born This Way.” Ahead of the performance, she talked to The New York Times about what spectators could expect:

Her already-iconic 2019 Oscars acceptance speech.

Okay, this one might not technically be underrated, but we love it so much we just had to include it. Lady Gaga took home the Academy Award for Best Original Song at the 2019 Oscars, thanks to her hit “Shallow” from A Star Is Born. The teary-eyed artist’s acceptance speech is pretty much required viewing for anyone with a dream.

We’re hoping Lady Gaga’s birthday is incredible this year. Because she deserves it.
