Florida Georgia Line's Tyler Hubbard is a gun owner who's in favor of universal background checks. He's among a growing crowd of people nationwide who've joined TOMS' End Gun Violence Together campaign.

In the 10 days since TOMS shoe company founder Blake Mycoskie announced a wide-ranging campaign to end gun violence, more than 600,000 have signed on to help him, including country's Hubbard and Dierks Bentley.

Both men took to social media with messages for their fans:

"As a proud gun owner myself that's a right and privilege I take very, very serious," Hubbard says. "I think we can all come together and all agree that something has to change. It's unacceptable. We shouldn't have to walk out of the house and live in fear any more."

Bentley tweeted support for TOMS and Mycoskie and pointed to the TOMS website, where people can send a postcard to their government representatives. According to a press release, 90 percent of Americans agree that there should universal background checks before you can buy a gun. This particular initiative was launched after the shooting at the Borderline Bar & Grill, which took place just miles away from the TOMS headquarters.

"Do your part to make this country a better place for our friends, our family and our kids," Hubbard says.

Joe Jonas, Ryan Seacrest and actor Josh Duhamel are other celebrities who've shown support for the campaign. TOMS also donated $5 million to organizations that are committed to addressing gun violence "through various tactics including programming in communities of color, mental health, research and policy, suicide prevention, and more."
