Blake Shelton and the Bellamy Brothers are bringing their 2019 tour to an end this weekend, and they celebrated early on Thursday night (March 22), joining up for a karaoke performance of the brothers' smash hit, "For All the Wrong Reasons."

Shelton performed one of the final dates of his Friends & Heroes Tour at Mohegan Sun Resort & Casino in Uncasville, Conn., and his tour entourage retired to a private karaoke bar in the casino to celebrate the tour's final weekend afterward. Shelton takes the stage in the video above, dressed casually and holding a drink as he launches into "For All the Wrong Reasons."

He's accompanied by the Bellamy Brothers, recreating their famous harmonies on the song's opening chorus as Shelton takes the third part.

"Why are you reading this?" Shelton demands comically as he sees Howard Bellamy looking at the lyrics from the karaoke machine. "You wrote it!"

As they swoop into the last chorus, Shelton exclaims, "I f--kin' love you!" before singing, "for all the wrong reasons," drawing smiles all around. Click on the video above to see the loose, fun performance.

"For All the Wrong Reasons" gave the Bellamy Brothers their fifth No. 1 hit when they released it as the lead single from their When We Were Boys album in 1982. Howard Bellamy wrote the song, which the brothers co-produced with legendary Nashville producer Jimmy Bowen.

Shelton's Friends & Heroes Tour also features Trace Adkins, John Anderson and Lauren Alaina. It launched on Feb. 14 in Oklahoma City, and Shelton will play another date in Uncasville on Friday night (March 22) before wrapping the tour with a gig at Times Union Center in Albany, N.Y., on Saturday (March 23).
