Poor, poor Kourt.
The source says of Disick:
Girls just want to have fun and that's exactly what the 2012 Miss USA contestants did while waiting for the big event in Las Vegas last week.
The lovely ladies got together and filmed themselves lip-syncing to Carly Rae Jepsen's Call Me Maybe for this adorable viral video (above).
The beauty queens weren't the only people involved either. Pageant hosts Andy Cohen and Giuliana Rancic got in on the fun too!
But mirror, mirror on the wall, who is the most adorable of them all?
Donald Trump, of course!
