The late Christina Grimmie's friends and fellow artists are keeping her memory alive.

The 22-year-old former Voice contestant was shot and killed during a post-concert meet-and-greet on Friday night, and on Saturday, Charlie Puth fittingly dedicated his hit song, "See You Again," to the late singer.

"I was reading the news last night and heard that my good friend Christina Grimmie was killed, and I want to dedicate this song to her tonight," an emotional Puth said during his performance at the BLI Summer Jam in Wantagh, New York. "I’ve been upset about this all day, mainly because I just never got to say what I wanted to say to her, and I feel like this song perfectly captures that.”

Puth's "Marvin Gaye" collaborator, Meghan Trainor, also took some time out of her own performance during her slot at BLI Summer Jam. The "Me Too" singer dedicated her performance of "Like I'm Gonna Lose You" to Grimmie.

"So, if you will, please sing it with me as a shoutout to our girl Christina," Trainor said. "This one's for her. Let's sing nice and loud."

"We love you @therealgrimmie ❤," she also captioned a video she posted of the touching moment on Instagram.

Trainor and Puth aren't the only singers honoring the YouTube sensation. Fifth Harmony took a moment in NYC to reminisce about meeting Grimmie, calling her "so humble."

A fan video also captured Justin Bieber singing "Grimmie, can you hear me?" during a performance of his song "Purpose" at a Winnipeg tour stop on Saturday.

Meanwhile, Kesha gave Grimmie's loved ones a shoutout during her performance at a Pride celebration in Pittsburgh, Pennsylvania.

"Send a little love to the family, friends and fans of Christina Grimmie," Kesha told the audience.

A cappella group Pentatonix expressed their "heartbroken" feelings while performing in Munich, Germany, on Saturday night, when the group dedicated "Light in the Hallway" to the late singer.

Following Grimmie's tragic death, the Voice family -- including Blake Shelton, Christina Aguilera, and her season six coach, Adam Levine -- expressed their sorrow.

"I'm stunned and disgusted and heartbroken that we lost that sweet little girl... Keeping @TheRealGrimmie family in my heart and mind," Shelton tweeted on Saturday.

Meanwhile, Levine will pay the expenses for Grimmie's funeral, the Maroon 5 frontman's management confirmed to ET on Monday.

"[My wife] Behati and I are absolutely devastated and heartbroken by Christina Grimmie's tragic death," Levine said in a statement obtained by ET on Saturday. "Our hearts go out to her family. Christina was a natural, a gifted talent that comes along so rarely. She was taken from us too soon. This is yet another senseless act of extreme violence. I am left stunned and confused how these things can conceivably continue to happen in our world."
