Chris Martin joins 'The Voice' as mentor

Coldplay frontman Chris Martin has joined singing reality show 'The Voice' as a mentor in the new format.
The 37-year-old singer will be a guest mentor for the second round of battles, and will act as a "universal advisor" to the rest of the coaches, the Hollywood Reporter said.
He will also aid all of the show's contenders during 'Battle Rounds: Round 2,' which commences from March 31.
The new format will have each contestant paired up and then sing the same song separately in a sudden-death match.
The knockout stage was almost leaked weeks ago at a 'Voice' screening in New York City, hosted by executive producer Mark Burnett, host Carson Daly and mentor Usher.

"Every season, we do reserve the right to look back and say, how do we tweak this show to keep what's important, authentic music and the highest level on talent onscreen, with four of the biggest people in music? And with that do come some tweaks. There might be some surprises this year," Daly said.
Apart from appearing on the March 31st episode, Martin will also feature on the NBC show on April 1st and April 7st.
