Gwen Stefani wasn't going to let her busy schedule keep her from supporting her country boyfriend.
A fan noticed a crew member on the app with Stefani so she can see the show and he took to Twitter to note the gesture.
"A guy standing next to me at the Blake concert was facetiming Gwen Stefani, so that's pretty cool," he wrote.
Stefani liked a Twitter photo taken by a fan during the concert. It showed Shelton, slinging his guitar, standing in the spotlight with his arms open wide.
Shelton and Stefani were first seen together last fall.
In a recent appearance on Jimmy Kimmel Live, Stefani admitted that her new single "Make Me Like You" is about "The Voice" coach.
