Other local celebrities including Justin Timberlake, Jessie James Decker and Brittany Aldean also took to social media to pay tribute to the victims.
Christian singer Lauren Daigle was supposed to host a concert in Nashville on Monday night celebrating the release of her new album -- but instead called off the gig to host a vigil for the community following the deadly shooting at The Covenant School.
Six people -- three children, all aged 9, and three adults -- were killed at the Nashville elementary school earlier in the day.
"Today's shooting is truly heartbreaking for our Nashville community and all of those impacted," said the singer. "I'm going to postpone my performance tonight, and in its place, host a community-wide Prayer Vigil."
"To those in the local Nashville area, if you need a safe place to come pray, mourn, and be with your community, please join us," she continued. "The doors are open for all."
