Supportive girlfriend or the most supportive girlfriend?

Distance couldn’t keep Gwen Stefani from watching Blake Shelton‘s Detroit concert over the weekend, as the singer reportedly used FaceTime to watch the performance at the Palace of Auburn Hills.

“A guy standing next to me at the Blake concert was FaceTiming Gwen Stefani, so that’s pretty cool,” Twitter user Kevin Nisun wrote on Saturday.

(Nisun could not immediately be reached for comment.)

Shelton also took to the social media website after the show, writing, “Thank you Detroit. Just wow. Thank you!!!!!”

The country singer, 39, has also played a part in Stefani’s music since they started dating last year. Stefani’s latest single, “Make Me Like You” – which debuted during the Grammys – is about Shelton.

She will also serve as Shelton’s advisor for The Voice in the upcoming season.

“We know we collaborate well together as coaches, so of course I would have her as my mentor, and she’s so smart and talented!” Shelton told PEOPLE.
