Taiwan pop singer Evonne Hsu is back in the limelight with the Chinese version of the title track of the Hollywood romance, "What Happens in Vegas ...".

The song titled "Chun Shu Yi Wai", or "Totally Unexpected", also marks the artist's comeback to the music world two years after suffering a serious waist injury.

Putting her best foot forward at a movie promo event on Wednesday, one could see no traces of the unfortunate accident that forced Evonne Hsu to quit dancing-something she'd been pursuing since age 12, reports Hong Kong-based publication Tungstar.

"What Happens in Vegas..." stars Cameron Diaz and Ashton Kutcher and tells the story of two strangers who get married after a wild night in Las Vegas and go on to win a jackpot together. While trying every possible way to keep all the money for themselves, the couple fall in love with each other. The 20th Century Fox release will premiere in Taiwan on May 9.
