Speaking ahead of her Vegas residency, which kicked off in June 2018, Gwen tweeted: "To be able to do a show in Vegas is such an incredible honour."
"Growing up in Anaheim, California, I could never have imagined one day having my own Vegas residency. I have been so fortunate to tour throughout my career, but to create a show for Vegas is something I've never experienced and I can't wait."
