Gwen Stefani [1]'s Las Vegas residency is officially underway! The 48-year-old singer opened her concert series on June 27 at Planet Hollywood's Zappos Theatre with some support and words of encouragement from her boyfriend [2], Blake Shelton.

Though her set list [3] includes both nostalgic No Doubt songs and solo hits alike, Stefani slipped in an unexpected cover of Rihanna [4]'s "Umbrella" on opening night. Stefani made it her own, however, by performing a characteristically edgier and more rock-sounding rendition of the 2007 banger. The "Just a Girl" residency [5] will run quite a long time through March 2019. Here's hoping that Stefani sprinkles other covers in her performances in the coming months!
