Looks like Celine Dion's recent voice problems, which caused her to cancel a slew of Las Vegas concerts earlier this year, are completely cleared up.

The diva was the closing act at the annual Walmart shareholders meeting in Arkansas on Friday, and brought down the house with her songs "The Power of Love," "Love Can Move Mountains" and "It's All Coming Back to Me Now."

The shareholders meeting, which is always a star-studded event, was hosted by Justin Timberlake, and also included a performance by Lionel Richie, who sang "Easy" and "All Night Love."  Taylor Swift performed as well, but her set wasn't included on the webcast of the event due to a request from her record label.
