Fortunately, when famous people drink there are usually cameras rolling. While we cannot personally attest to the level of intoxication of the musicians in these videos, I think we all know some outlandish behavior when we see it. Enjoy!

10) Britney Spears

There was a time, not so long ago, when Britney Spears wasn't such a troubled soul. Back in the day she was just a quiet, well-mannered girl who liked to engage in deep, intellectually stimulating conversations with her boyfriend. Watch here as she enjoys what appears to be fine cuisine and discusses philosophy, time travel, and the importance of "Carpe Diem".

9) Slash

This video starts off with Axl asking the crowd if they know where they are. He probably should have asked that question to his band.

Check out this clip where Slash completely drops the ball on the opening of Welcome to the Jungle. I'm surprised this band didn't stay together longer...

8) Tommy Lee/ Kid Rock

Drunken moment or highly- crafted publicity stunt?

With some of these industry vets, it's hard to tell. A quick VMA scuffle between Kid Rock and Tommy Lee last month definitely created the media buzz necessary to boost album sales for Rock's new album.

Is it just me, or does the backdrop of Alicia Keys covering a George Michael song make this funnier?

7) Elvis

I think that, deep down, everyone wishes their life was like this Elvis clip. While his level of intoxication is up for debate, he's clearly mumbling some incomprehensible gobbledygook. Even though I'm totally with him in the beginning, by about 20 seconds in I realize that he's not making sense.

Even worse, I realize he's hardly made any sense all along.

The rant continues until there is a heart-wrenching uncomfortableness about him and then…out of nowhere….BOOM! He's singing with a smile and he's back on top, baby

6) Avril Lavigne

Hey! Hey! You! You!

I'm your drunken Girlfriend!

I threw up! On your shoes!

I think you need some new ones!

Hey Hey! You you!

I'm your drunken girlfriend!

Booze are fine

Drink all the time

They're so delicious

I think about them all the time

They're not addictive!

Don't you know how much I drink?

It makes me feel all right

Bartender, over here!

I want some vodka, maybe beer?

Better yet I'll make some Alize disappear!

I know I'm never drinking Tanqueray ever again (ever again, ever again)

6) James Brown

Wasted in America! James Brown sure did keep things fun. RIP.

5) The Hoff

This is your brain:

This is your brain on the Hoff:

Any questions?

4) Courtney Love

You've probably already seen this. Thus, you know why it made the top 5. Nothing is more fun than watching Madonna get shaken up.

3) Amy Winehouse

Selecting just one drunken Amy Winehouse moment to share is no easy task. This one stands out above others only because you can see the dismay on Charlotte Church's face as she attempts to hold together this duet on "Beat It." Good times. No, great times.

2) Diddy

Five words: Silky. Smooth. Cocoa. Butter. Skin.

1) Scott Stapp

Watching this is like listening to Arms Wide Open. You might not feel proud at the time, but secretly, you know it felt good. You KNOW it did! This might be the most entertaining thing Scott Stapp has ever done. Actually, this might be the funniest video ever.
