Last night, Wednesday, Dec. 8, Little Big Town performed two songs off of their latest album 'The Reason Why' at 'Jimmy Kimmel Live!' Equipped with a full backing band, the quartet kicked off their two-song set with their latest single 'Kiss Goodbye.' Phillip Sweet sat playing piano as he sang along with fellow LBT member, Karen Fairchild, who looked stunning in a black sequined dress.

After the band played 'Kiss Goodbye' -- a slower song about heartbreak -- Little Big Town closed the show with a bang, performing their Grammy-nominated single 'Little White Church.' The irresistibly catchy song had the crowd clapping, dancing and singing along. Even though it was difficult to focus on anyone besides Fairchild and Kimberly Schlapman -- who was also decked out in a glittery number -- it's nice to see that the members of Little Big Town have no problem sharing the spotlight. Sweet and Jimi Westbrook rocked out on their guitars and provided backing vocals on the chorus as the two female singers belted out the lyrics.

Before the show, Jimi Westbrook also tweeted about meeting 'Crazy Heart' actor and country music fan Jeff Bridges. Even though Little Big Town have been performing together for over 10 years, Westbrook definitely sounded starstruck. He wrote, "I just met Jeff Bridges @jimmykimmel... holy crap!! Jimi" on the band's official Twitter page.
