Chris Martin Helps Coaches on 'The Voice' - See All the Photos!

Viewers of The Voice on Monday (March 31) were in for a treat as Chris Martin made a special guest appearance!

The 37-year-old Coldplay singer joined all four of the coaches – Adam Levine, Blake Shelton, Shakira, and Usher – to help them and their contestants prepare for their performances during round two of the Battles.

Chris and his wife Gwyneth Paltrow announced last week that they have separated after more then 10 years of marriage, though it seems they are still great friends.

The still married couple was spotted over the weekend vacationing together in the Bahamas. Check out the photos right now!
