Eminem is Berzerk. Slim Shady is a misunderstood artists and only Rihanna understands him in the new music video for Eminem's new single "The Monster." The sexy Caribbean singer is Eminem's therapist and it looks she's putting him through a past life regression.

Eminem's past life brings him from the couch to a straitjacket under the watchful eye of his sexy shrink Rihanna. "The Monster," is Eminem's fourth single from his new album "Marshall Mathers LP 2."

 Rihanna makes a terrific but flawed psychiatrist for  Eminem in the new video which was directed by Rich Lee. Rich Lee also directed music videos for Eminem's "Rap God," "Not Afraid," and "Lighters".

Rihanna runs Eminem through a televised retelling of his career from old music videos like "My Name Is,"  "Lose Yourself" and The Way I Am," through news footage and a shot of Eminem's Grammy performance with Elton John.

 "The Monster" knocked Miley Cyrus' "Wrecking Ball" out of the number one singles spot before it was  passed by the nine-week number one run from Lorde for her new song "Royals." The Marshall Mathers LP 2 is just about to hit sales of a million and a half in sales. And Christmas is still a week away.

"The Monster" lyrics:

I'm friends with the monster that's under my bed

 Get along with the voices inside of my head

 You're trying to save me, stop holding your breath

 And you think I'm crazy, yeah, you think I'm crazy

I wanted the fame, but not the cover of Newsweek

 Oh, well, guess beggars can't be choosey

 Wanted to receive attention for my music

 Wanted to be left alone in public. Excuse me

 For wanting my cake and eat it too, and wanting it both ways

 Fame made me a balloon 'cause my ego inflated

 When I blew; see, but it was confusing

 'Cause all I wanted to do is be the Bruce Lee of loose leaf

 Abused ink, used it as a tool when I blew steam (wooh!)

 Hit the lottery, oh wee

 With what I gave up to get was bittersweet

 It was like winning a used me

 Ironic 'cause I think I'm getting so huge I need a shrink

 I'm beginning to lose sleep: one sheep, two sheep

 Going cuckoo and cooky as Kool Keith

 But I'm actually weirder than you think

 'Cause I'm

I'm friends with the monster that's under my bed

 Get along with the voices inside of my head

 You're trying to save me, stop holding your breath

 And you think I'm crazy, yeah, you think I'm crazy

 Well, that's nothing

 Well, that's nothing

No, I ain't much of a poet but I know somebody once told me

 To seize the moment and don't squander it

 'Cause you never know when it all could be over tomorrow

 So I keep conjuring, sometimes I wonder where these thoughts spawn from

 (Yeah, ponder it, do you want this?

 It's no wonder you're losing your mind, the way it wanders)

 Yo-lo-lo-lo-yee-whoo

 I think you've been wandering off down yonder

 And stumbled onto Jeff VanVonderen

 'Cause I need an interventionist

 To intervene between me and this monster

 And save me from myself and all this conflict

 'Cause the very thing that I love's killing me and I can't conquer it

 My OCD is conking me in the head

 Keep knocking, nobody's home, I'm sleepwalking

 I'm just relaying what the voice in my head's saying

 Don't shoot the messenger, I'm just friends with the

I'm friends with the monster that's under my bed

 Get along with the voices inside of my head

 You're trying to save me, stop holding your breath

 And you think I'm crazy, yeah, you think I'm crazy

 Well, that's nothing

 Well, that's nothing

Call me crazy, but I had this vision

 One day that I'd walk amongst you a regular civilian

 But until then drums get killed and I'm coming straight at

 MCs, blood get spilled and I

 Take it back to the days that I get on a Dre track

 Give every kid who got played that

 Pumped up feeling and shit to say back

 To the kids who played 'em

 I ain't here to save the fucking children

 But if one kid out of a hundred million

 Who are going through a struggle feels and then relates that's great

 It's payback, Russell Wilson falling way back

 In the draft, turn nothing into something, still can make that

 Straw into gold chump, I will spin Rumpelstiltskin in a haystack

 Maybe I need a straight jacket, face facts

 I am nuts for real, but I'm okay with that

 It's nothing, I'm still friends with the

I'm friends with the monster that's under my bed

 Get along with the voices inside of my head

 You're trying to save me, stop holding your breath

 And you think I'm crazy, yeah, you think I'm crazy

 Well, that's nothing

 Well, that's nothing
