The Voice is pulling out all the stops as the NBC competition series nears the end of its first season.
Stevie Nicks, Train's lead singer Pat Monahan and OneRepublic frontman Ryan Tedder will join previously announced Miranda Lambert in performing with The Voice finalists.
Nicks will duet with Javier Colon, Monahan will perform with Vicci Martinez and Tedder will sing with Beverly McClellan on The Voice's season finale on Wednesday at 8 p.m. Lambert, who is married to musician coach Blake Shelton, is set to perform with Dia Frampton.
The Voice airs its penultimate episode Tuesday at 9 p.m. It will return for Season 2 in early 2012; the series also snagged the plum post-Super Bowl spot.
