Christina Grimmie would have turned 23 today, so let’s take a moment and reflect on our favorite moments of her career.

When she performed a beautiful cover of “Titanium” before she was on The Voice.

When she gave an incredible performance of “Wrecking Ball” during her audition for The Voice.

When she sang “All of the Stars” with Ed Sheeran.

When she covered Mariah Carey and Miguel’s "Beautiful" during a visit to On Air with Ryan Seacrest.

When she teamed up with Selena Gomez for a Xbox Kinect commercial.

Her music video for “Tell My Mama."

Her tribute to her fans through her “Feelin’ Good” music video.

Last, but definitely not least, her beautiful new song, “Invisible” which proves just how powerful music can be.

Gone, but never forgotten. We love you, Christina. Happy birthday!
