You know Mary Lambert as the velvety-voiced hook singer on Macklemore and Ryan Lewis' "Same Love." Tonight, the 24-year-old will take the GRAMMY stage alongside the one-and-only Madonna. She tells Fuse News anchor Jack Osbourne that she's come a looong way since the last GRAMMYs.

"I was bar tending last year!" the singer, up for two awards tonight, tells Fusejust like UK Singer-Songwriter Sam Smith.

While she remained mum about details of her performance with Mack and Madge, the Seattle singer did give us one teaser: "I heard there'll be a kiss." When Jack asked if they'd be reenacting Madonna's infamous smooch with Britney Spears, Lambert gushed "Hopefully!"
