One fun thing about having Gwen Stefani return to the cast of hit reality show The Voice—her fellow coaches Blake Shelton, Kelly Clarkson and John Legend can indulge in some unabashed '90s nostalgia, as they did following this week's premiere of the show on Monday and Tuesday (Sept. 23-24).

Stefani, who is a returning alum of the show—the very show where she met her current boyfriend, Shelton, four years ago—posted a video that has all four coaches collaborating on a version of her 1995 trademark heartbreak hit with No Doubt, "Don't Speak." The song was written by Stefani and her older brother, tweaking the composition to reflect her breakup with bandmate Tony Kanal back in the day.

While it's funny to hear Shelton chime in with a line here and there, and Legend's piano playing is on point, Stefan's harmonies with Clarkson are actually a little goosebump-worthy. The two take the lilting, sad song to another level with almost heavenly dual vocals. The song is "no doubt" a classic, but the fact that it's brought to life more than 20 years later so beautifully speaks to its longevity.

The Voice airs Mondays and Tuesdays on NBC at 8PM ET, with Stefani, Shelton, Clarkson and Legend in the coaching chairs.

Shelton tickets are still available to all of his shows still slated for 2019.
