LOS ANGELES, April 30 (UPI) -- Gwyneth Paltrow surprised The Roxy attendees Monday night as she joined Jason Isbell's opening act Holly Williams as a backup singer.
After the first song, Williams introduced the 41-year-old actress, saying it was "awesome" to have her on stage. The two later sang a duet to "Waiting on June," from Williams' 2013 album, The Highway.
