Shania Twain debuts Las Vegas show at Caesars Palace

Shania Twain unveiled her Las Vegas show, "Shania: Still the One," last night at Caesar's Palace in Las Vegas, which officially ends the country superstar's eight-year performance hiatus.

Twain's 90 minute hit-packed extravaganza is booked for a two-year residency at Caesar's 4,300 seat Colosseum Theater, although the current run will last only until Dec. 15 and then resume March 19, 2013.

According to a detailed report from Billboard, Twain's setlist includes mega-hits like "Still the One," "From This Moment" and "That Don't Impress Me Much" and favorites like "Man! I Feel Like a Woman!" and "Whose Bed Have Your Boots Been Under?"

Twain tells People that she's "never had a show this exciting before" and credits her renewed career confidence to her husband of nearly two years, Frédéric Thiébaud, saying: "I need that support. I just need what we have. It grounds me every day and reminds me that there are a lot of important things going on in the world."
