The rumors of the feud between the two American Idol winners have been burning since last year and people can’t help but ask if they are really on good terms.

And following the event, Clarkson told Entertainment Tonight that taking photos was her way of trying to shut down any rumors about their non-existent feud.

“Everybody always tries to pit me and Carrie against each other. So, when I saw her I was like, ‘You know what? Let’s just end this right now and get a picture together because we are never in the same place.’ And, like, it never happens. And people always try to put it together like we’re enemies. And I’m like, ‘We don’t even know each other well enough to be enemies.’ So, anyway, I went to get a picture and then everybody lost their mind.”
