After Emma Stone tried her hand at the Tonight Show's Singing Whisper Challenge, we've learned that lip-reading is definitely not the La La Land actress's strong suit.

During her appearance Thursday, the red-headed stunner wore noise-canceling headphones as she guessed host Jimmy Fallon's song by reading his lips. Her stunned face said it all during her first attempt as Fallon whispered the lyrics to Bruce Springsteen's hit "Born in the U.S.A," which Stone laughingly informed him "looked inappropriate."

Success seemed far and so Fallon completely dropped the whisper portion of the challenge and belted out his tunes, which helped only slightly. After several minutes of failed guessing, Stone did finally name the correct tune.

The Tonight Show emcee fared slightly better during his portion and quickly picked up Britney Spears's "... Baby One More Time," complete with suggestive hand gestures, though after shooting back at Stone: "Eat—what you're saying is inappropriate!"

Fallon then sang the festive hit "Blue Christmas" complete with an Elvis impression—but to little avail.

"Oh my God, this is so difficult," the actress admitted as she wiping her eyes from laughter. "I wish you guys could be in my head." Just when we thought we couldn't have a bigger crush on the Crazy, Stupid Love star!
