Shania Twain makes her debut on The Voice Monday night (April 24) and according to a sneak preview, everyone on the reality competition is starstruck by the legendary country singer.

From awed contestants to admiring judges — even Blake Shelton says, "I still can’t believe you’re here," — Twain’s undeniable star power seems to have already had an impact on the show.

Twain will act as a key advisor to Season 12's Top 12 contestants. She’ll fit a similar role to artists such as Luke Bryan, Celine Dion, John Legend and other stars who have served as guest advisors and mentors on the show. Current The Voice coaches Shelton, Gwen Stefani, Adam Levine and Alicia Keys will also continue to coach contestants down the final stretch, alongside Twain.

It’s not Twain’s first go-around on a TV singing show, as she previously appeared on season nine of American Idol in 2010, but the singer has been scarce since she stepped away from the spotlight in the early millennium.

Twain’s last album, Up!, was released in 2002 and after a several year break, a Las Vegas residency brought her consistently back onstage from 2012-2014. In 2015 she also embarked on her Rock This Country Tour, her first major tour in over a decade. There have been rumblings of a new Twain album, but the singer has yet to release her rumored spring single.

However, new album or not, Twain's legendary career will be the subject of an exhibit at Nashville’s Country Music Hall of Fame and Museum this June. Perhaps that will coincide with a new single?
