The Voice's Season 16 finale on Tuesday (May 21) fairly blew the roof off in terms of celeb talent. In addition to scoring A-list duets for each of its Top 4 finalists the night of the big winner reveal, the show also recruited some of the most wildly popular names in music for pure performance value—namely Taylor Swift, the Jonas Brothers and ultra-hot K-popsters BTS (who showed up despite a kerfluffle regarding whether they were actually hitting the stage or just hyping the show itself).

So, anticipation was high, indeed, but the finalists were able to hold their own. With Blake Shelton having three contestants in the finals, the finale pumped right along on a mostly country-based level.

True to that vibe, Finalist Dexter Roberts was given the chance to sing with Toby Keith on the superstar's name-checking new single, "That's Country Bro," an up-tempo-guitar-driven track lyrically consisting of a long list of callouts to classic country stars.

Not surprisingly, Roberts' friendly personality and clear, mid-range vocals jibed neatly with Keith's down-home vibe and deeper voice. Both artists strummed guitars as they called out everyone notable in country including ... "Dexter," as Keith memorably finished off the song.

"It's hard to be around Dexter and not like the guy," explained coach Shelton. "He's such a nice unassuming guy that everybody should get a chance to meet one of these days!"
