Sadly, Kris Allen posted on Twitter that he was cancelling his Tonight Show with Conan O’Brien appearance on Wednesday due to a death in his family (Allen’s grandmother passed away). American Idol finalist Allison Iraheta will be filling in on Conan.

Kris Allen tweeted: “I know I was supposed to do conan on wed, but there was a death in my family. But everyone watch @Allison4Realzzz on Wed. She is filling in.” He followed it up with “by filling in I mean @Allison4Realzzz is gonna rock Conan’s face off on Wednesday.”
