The country star will perform at London's Royal Albert Hall on June 21 in support of her forthcoming album Blown Away.
Speaking to Digital Spy about the show, Underwood said: "I'm starting at the top! I've been to the UK for pleasure before, but I've never been there as a singer.
"I'm curious as to how I will be received and if people will actually show up! I so hope they do."
She added: "I'm excited to get to play in such a big venue and I'm going to bring a little bit of home with me.
"It will be an awesome show, of course! There will be a lot of the new stuff along with some of my hits. Me and my band do a really good job of bringing the music first and I love to sing more than anything in the world."
Tickets for the show go on sale from 9am on April 27 and are priced between £22.50 and £45.
Underwood's new single 'Good Girl' will be released in the UK on May 7, while album Blown Away will follow on June 18.
