An easy mistake to make, in fairness.

Ellen recently celebrated her 60th birthday at a party organised by her wife Portia de Rossi and the guest list was impressive, to say the least.

It included the likes of Drew Barrymore, Kanye West, Gwyneth Paltrow, The Weeknd, Michael Keaton, Oprah Winfrey, Bruno Mars, Kim Kardashian West, John Legend, Pink and Adele.

One other guest was comedian and actor David Spade who had quite the hilarious recollection of the party. One particular highlight was him mistaking Ellen for someone entirely different.

"In fairness, I thought you were Justin Bieber for the first half hour—but it's only because your haircut! Not what you were wearing. You look great!" he said.
