In the clip, the 35-year-old model, wearing a flowing white dress and sporting a bob parted to the side, walked down a grand staircase as she sang a Marilyn Monroe-style rendition of "Happy Birthday."
In Schumer's recreation, the comedian flipped her blonde hair to the side and wore a pink tank top that read, "Boat hair don't care," as she walked down what appeared to be the same staircase and sang "Happy Birthday" in a similar way that Teigen had.
"Tribute," Schumer captioned the clip. "... We love you @chrissyteigen."
"Oh it's on," Teigen commented in response.
The video drew many celebrity fans, with Tan France commenting the crying laughing emoji and Katy Perry questioning, "wait do you guys live together now?"
Teigen and Legend weren't the only A-listers at the former president's birthday party. Other reported attendees included Alicia Keys, H.E.R., Gayle King, Steven Spielberg, Dwyane Wade, Gabrielle Union, Bradley Cooper, Oprah Winfrey, and Don Cheadle.
