Howard Stern 'can't stand' Jay Leno

Howard Stern has confessed that he "can't stand" Jay Leno.

The longtime radio host told Late Show's David Letterman that "he never liked Jay".

Stern also promised to help Letterman take on Leno's Tonight Show replacement, Conan O'Brien.

"We gotta beat this Conan. I mean for God's sake, how are you feeling that Jay left late night television and now we got a new guy we gotta compete with," the 55-year-old said.

Stern added: "Dave put me on national television many, many years ago before I was known. And I have stuck with Dave."
