Being a celebrity like Gwen Stefani and Blake Shelton can put a strain on personal relationships - traveling all over the country and working odd hours, but Stefani proved she can still be the most supportive girlfriend when she watched Shelton's Detroit concert last weekend. The Voice Judge and singer reportedly used FaceTime to view her boyfriend's concert performance.

Shelton may be probably too busy to notice that he's being filmed for his girlfriend. The crooner, wearing a black shirt and jeans sang his hits with his trusty guitar. According to someone in the audience, Stefani apparently called a friend so that she wouldn't miss her boyfriend's show. Hopefully that friend had enough phone battery to stream the whole concert.

"A guy standing next to me at the Blake concert was FaceTiming Gwen Stefani, so that's pretty cool," wrote Twitter user Kevin Nisun. While another fan posted on Instagram this caption, "A guy backstage tonight was next to a crew member face timing Gwen so she could watch Blake in concert! #gwenstefani #blakeshelton #tonight #gwenandblake #blakeandgwen."

Gwen Stefani and Blake Shelton has not been shy at all after their respective divorces. The couple has been displaying their love for each other publicly that it would not be a strange thing to see the doting girlfriend FaceTiming her man.

Shelton ended his concert with a thankful appreciation and also tweeting out to Detroit "Thank you Detroit. Just Wow. Thank you!!!"

Do you think Gwen and Blake are #relationshipgoals?
