Selena Gomez, 29, was a very special guest on the October 18 edition of The Late Late Show with James Corden. She wowed in an off-the-shoulder black dress for her performance with Coldplay. Selena and the band sang a beautiful rendition of their new collaboration “Let Somebody Go,” their first time singing the tune live. The song is from Coldplay’s latest album Music of the Spheres.
