Exclusive Sneak Peek: Usher Duets With Romeo Santos for HBO Latino Concert Special [Video]

Get ready for the silky vocals of Bronx, N.Y.-born Latin-music artist Romeo Santos, who hit the stage in 2012 for his first solo concert tour, which sold out three shows at Madison Square Garden in New York. You may have missed this epic event live, but you're about to get an exclusive sneak peek at his onstage duet with R&B superstar Usher from HBO Latino's upcoming special "The King Stays King -- Sold Out at Madison Square Garden."

Usher joins Santos, "The King of Bachata," for a duet of "Promise," the second single from Santos's debut solo album, "Formula, Vol. 1," which went triple platinum and was Billboard's top-selling Latin album of 2012. And judging from the reaction of the screaming fans when Usher takes the stage, it's an event worth watching.

HBO's nearly two-hour concert special brings you the best of Santos's performance, along with behind-the-scenes interviews and never-before-seen footage. Santos is also joined by hip-hip mogul P. Diddy and reggae duo Wisin y Yandel.

"The King Stays King -- Sold Out at Madison Square Garden" premieres on May 3 at 8 PM on HBO Latino. The event will also air on HBO Go and HBO On Demand.
