The most talked-about moment of Sunday night’s Academy Awards wasn’t an actual award announcement – it was a musical performance.

Lady Gaga’s unanimously-praised performance of a Sound of Music medley garnered the most social media chatter during the broadcast – both on Facebook and Twitter.

According to Facebook, Lady Gaga’s The Sound of Music medley and Julie Andrews’ appearance onstage hit 214K People Per Minute (PPM) globally and 154K PPM in the US. It beat out other buzzed-about moments like The Imitation Game winning Best Adapted Screenplay, Eddie Redmayne winning Best Actor, and even Birdman‘s win for Best Picture.

And over on Twitter, Lady Gaga’s performance saw the biggest spike in Tweets per minute. @LadyGaga was also the most-mentioned celeb of the night.
