Blake Shelton, OneRepublic, Hannah Huston to perform at 'The Voice' semifinals

NBC's "The Voice" has lined up its slate of performers for the Season 11 semifinals. A press release from the network on Friday said that coach Blake Shelton, frequent guests OneRepublic and former finalist Hannah Huston will all perform during the Live Semifinal Results show on Tuesday, Dec. 6.

The three musical guests will make for a busy outing for the singing competition, because "The Voice" will have to fit these performances in in addition to revealing which three  of the Top 8 contestants have been voted through to the finals and three Twitter Instant Save performances to see who is named the fourth finalist. All of that will have to be done within an hour-long program.

Still, the show has always added more guests in the final weeks of every cycle and Season 11 is no exception. Shelton, who is bringing his latest single "A Guy With A Girl" from his most recent album If I'm Honest, continues the tradition of coaches showing off their talents during "The Voice" playoffs. He follows Alicia Keys and Adam Levine, the latter of whom just performed with his band Maroon 5 last week. (If this pattern holds, expect Miley Cyrus to get a solo performance during the finals.)

OneRepublic has been one of the most frequent guests on "The Voice," with multiple visits to the series as well as front man Ryan Tedder being recruited in multiple capacities during Season 5. Tedder co-wrote Season 5 winner Tessanne Chin's first single "Tumbling Down" and served as the battle rounds advisor for Team Adam during that cycle. His band last appeared on "The Voice" two years ago performing "Love Runs Out" and also just guested on the Italian version of the series in May.

Last but certainly not least, Hannah Huston will be the first contestant from Season 10 to return to the show. Huston finished in third place and was Pharrell Williams' final student for his final season as a coach on the show.

What's interesting about her arrival on Tuesday is that she'll be back before the winner. Normally the first returning artist "The Voice" brings back is whoever won the previous season, so the question is what's happened to Alisan Porter? The Season 10 champion's absence seems strange, but she may just not have music ready to perform after only winning a few months ago. Perhaps she'll surface during next week's finals - but the semifinals will keep audiences entertained with a solid lineup of guests too.

"The Voice" airs Mondays and Tuesdays at 8 p.m. on NBC.
