Chris Martin of Coldplay will offer his expertise to contestants on 'The Voice.' A surprise SnapChat revealed that the superstar will act as a mentor for three episodes, airing March 31st, April 1st, and April 7th.



Martin will assist all four judges--Shakira, Usher, Blake Shelton and Adam Levine-- in grooming their singing hopefuls to win 'Battle-Round' performances.

The Coldplay star has some extra time to contribute to the talents of others since his band's new record, 'Ghost Stories,' isn't expected to hit retailers until May 19th.
