London, July 22 - Country singer Shania Twain has filmed a cameo in a new commercial for the Las Vegas hotel which will host her comeback shows later this year.

The "You're Still the One" hitmaker is scheduled to begin a two-year residency at the Colosseum in Sin City's famed Caesars Palace resort Dec 1. And in a bid to help boost tourism, Twain has volunteered to star in a promotional advert for the lavish resort.

During the clip, Twain, wearing a fitted black jacket and oversized sunglasses, enters the shot and flashes a big smile for the camera as she walks into the lobby with her entourage, reports dailystar. co. uk.

The commercial also features a guest appearance by Celine Dion, who is midway through her three-year residency at the venue. (IANS)
