Heres the thing at the end of the day: We were friends.

The 38-year-old explained he knew Jackson as a friend, and they related to each other.

I really didnt give a s about famous people.

I was thoroughly unimpressed by them, he recalled.

So when I first met him I was like oh cool, youre that guy who sings songs.

I sing songs in school.

I think thats also one of the reasons why we got along.

To Rosenbaums disbelief, Culkin said that he and Jackson used to prank call people.

Jacksons peerless control over his voice meant that he could easily adopt accents and tones fit for pranks.

For me, its so normal and mundane, Culkin continued.

I know its a big deal to everyone else, but to me it was a normal friendship.
