Country superstar Brad Paisley has gifted a Nashville, Tennessee musician a new guitar after losing everything in the Christmas Day bomb blast.

Alleged suicide bomber Anthony Quinn Warner hooked up explosives to a recreational vehicle and warned passers-by of the explosion, which left three people injured and wrecked businesses and homes along Second Avenue.

Buck McCoy was among those left homeless by the blast, documenting the devastation caused to his apartment on social media, while revealing his beloved cat Molly had been scared off and run away.

He has since been reconnected with his furry friend, who was found by authorities roaming the streets on Thursday, and now McCoy has also been given a helping hand by fellow Nashville resident Paisley, who saw a news piece about his pet reunion on TV and decided to send him a guitar so he could get back on stage with his band at Legend's Corner.

The Whiskey Lullaby hitmaker additionally invited McCoy to help himself to unlimited groceries from his charitable shop, simply named The Store, which provides food for locals in need, days after drawing attention to a crowdfunding campaign set up for McCoy on GoFundMe by sharing the link on Facebook.

He captioned the link: "Hey y'all, let's help Buck. It's Nashville. That's what we do."
