Celebrities weren't celebrating with Leonardo DiCaprio over his Oscars win — they were Leonardo DiCaprio.
Using the MSQRD app, celebrities swapped faces with DiCaprio at the Vanity Fair Oscars after party, and the results were recorded and uploaded to the publication's YouTube channel.
Everyone from Jessica Alba to Michael Strahan, Kate Upton, James Corden, and even DiCaprio's own mother used the app to see what it would be like to become the Oscar-winning actor himself.
"Oh, so this is me as Leonardo DiCaprio? It's not too different, is it?" joked James Corden upon seeing DiCaprio's face on his own using the app.
"I knew this was foretold the minute I climbed inside that dead horse — I knew I was getting an Oscar," Conan O'Brien says.
And there's plenty more where that came from.
