Actress Sandra Bullock appeared as a surprise guest and hit the stage to play the guitar last night in front over over 15,000 people (Tues. Jun 22) at the “Nashville Rising: A Benefit for Flood Recovery” concert at Bridgestone Arena in Tennessee.

The event, hosted by Faith Hill and her husband Tim McGraw, was held to help provide relief aid for flood victims and also featured performances from Taylor Swift, Carrie Underwood, LeAnn Rimes, Miley Cyrus and more. Nashville native Reese Witherspoon even checked in via a video greeting because she couldn’t make it there in person.

“I’m going to bring the house down,” Bullock, 45, declared to the sell-out crowd of more than 15,000 people as she swung an acoustic guitar over her shoulder. “And I’m going to do it Nashville style!” First telling the audience, “If I could have some quiet, please,” Bullock slowly, and awkwardly, picked out the opening notes to “Smoke On the Water.”

“I can’t play for crap!” she eventually deduced before introducing Faith Hill, who joked, “Sign that girl right away.”

All jokes aside, when all was said and done, the concert raised over $2 million for flood victims.
