Watch MGK & Jelly Roll perform “Lonely Road” in Las Vegas

Jelly Roll joined Morgan Wallen as a special guest for his concert at Allegiant Stadium in Las Vegas and had a surprise for his fans up his sleeve.

The “Need a Favor” star welcomed MGK to the stage to perform their latest collaboration, “Lonely Road.” “Lonely road, take me home/ To the place we went wrong/ Where have you gone now?/ It was a ghost town/ And I'm still here all alone,” they sing together on the chorus.

“Lonely Road” hit streaming services on Friday (July 26), which features an homage to John Denver's 1971 tune “Take Me Home, Country Roads.” Referring to themselves as KellyRoll, MGK revealed worked on “Lonely Road” for “2 years, 8 different studios, 4 different countries, [and] I changed the key 4 times.”

In the corresponding music video, the duo are joined by MGK's girlfriend, actress Megan Fox, and Jelly's wife, Bunny Ho, who both have prominent roles in the emotional clip.

The collaboration marks MGK's first release since revisiting his own Hotel Diablo deluxe edition album earlier this month. For Jelly Roll, it follows his recent appearance on Eminem's new album The Death of Slim Shady (Coup De Grâce)where he participated in the emotionally charged track “Somebody Save Me”.
