Awkward! Ellen DeGeneres celebrated her 60th birthday with a huge star-studded bash on Feb. 10, and unfortunately, not all of her guests were friendly with each other. As a matter of fact, P!nk took the stage to perform her hit “What About Us”, while longtime enemies Kim Kardashian and Kanye West were in the crowd. That must have been incredibly uncomfortable after their long history of feuding!

“How is this my life, I mean all of my idols were in one room and they were there for me,” said Ellen, revealing that Diddy, Oprah, Adele, and more were also in attendance. “It’s so weird, I know so many different types of people, and that’s what so great about it. It was a really crazy mix of people, and you assume everyone knows everyone.” And yet, someone people knew each other for the wrong reasons.

Kim and P!nk have a shaky past, beginning in March 2016 when Kim posted her infamous naked mirror selfie. Bette Midler mocked it, saying that Kim would have to swallow the camera to show fans new parts of her body, and Kim responded by saying, “Hey @BetteMidler I know it’s past your bedtime but if you’re still up and reading this send nudes #justkidding.”

Thats when P!nk decided to speak up, writing a long post about using your “brain and not your body.” P!nk reignited the feud over a year later in October 2017 when she went on Watch What Happens Live and confirmed that the post was about Kim, saying “Honestly she went in on Bette Midler and if you go in on Bette Midler, you’re going to hear from me.” Kim got her final say in February, 2018, when she sent P!nk one of her special-edition Valentines Kimoji fragrances and included her on her list of “haters.” Watch the video below to see Kim take another shot at P!nk.

It’s unclear whether Kim and P!nk ran into each other at the party, but it sounds like Ellen was none the wiser to the potential drama. “I am so thankful to everybody for coming and thank you, Portia, you put on the most amazing party,” she said. “It was just a party I will never forget.”
