The singer, a native of Evesham Twp., N.J., rocketed to stardom on YouTube and as a contestant on "The Voice."
But her young career was cut short when she was gunned down following a concert in Orlando on June 10. She was 22 years old.
Grimmie won the Choice Web Star for the music category Sunday night, beating out Boyce Avenue, Chloe X Halle, Cimorelli, Johnny Orlando and MattyBRaps.
While it's an honor to win, many pointed out that FOX didn't mention Grimmie's name once during the ceremony, even when an entire segment of the award show was dedicated to ending gun violence.
The segment featured actress Jessica Alba, artist Ne-Yo, and victims from San Bernardino, Newton and Orlando taking to the stage.
The group asked the audience to stand and urged everyone to post on social media using #StopTheViolence.
"Tonight, we stand together with these teens united in a call for peace and an end to this violence," Alba said. "Now, more than ever, we need to stop, feel and ask, 'What's going on?'"
But with so much focus on ending gun violence, many questioned how FOX could've left Grimmie out of the award show after her death to gunman Kevin Loibl took over headlines less than two months ago.
The Teen Choice Awards consist of 50 individual awards, so the ceremony cannot accommodate each winner with the surfboard trophy during the televised award show.
Still, many took to social media to voice their displeasure that the Teen Choice Awards didn't pay tribute to Grimmie, let alone acknowledge her once during the show.
It's sad how they did not even mention #ChristinaGrimmie tonight on the tca...smh— J A Y (@babydubs_) August 1, 2016
