In an interview with "Good Morning America," the three-time Grammy Award winner admitted that it's easy for her to forget how much she loves performing live until she takes the stage again.

"I don’t miss it at all. I'm so good to do my kids and do mom and hang out with my cute Blakey and all that but then when I get up there I realize it's in there still and I'm like, 'OK, I need this attention still. I like it,'" she said with a laugh. "So, it's always been there. It's whatever the gift that God gave me and I feel so grateful and I feel so humbled and honored to be in Vegas. To do a show like this, it's just another level and it's challenging in another way."

Stefani, 48, assembled a show replete with personal touches, including home videos and photos that her father took throughout her childhood. The idea she said, was to let fans in on both the ups and the downs of her life -- with the present, she gushed, being a "really amazing place." One reason? Her two-year long relationship with her boyfriend, country singer Blake Shelton.

"He's my homeboy. He's my homey. He's just really an amazing all-around human so I feel so grateful for that," she said. "I celebrate him in the show! He's inspired me so much. He's changed my life."
