Justin Bieber Tops List Of Celebs We'd Love To See With A 'Hangover'

Justin Bieber in The Hangover

Love Mel Gibson or loathe him, you have to admit you were at least interested -- if not excited -- to see what he'd do with his cameo as a Bangkok tattoo artist in "The Hangover 2." Sadly, some cast and crew unrest put the kibosh on that, and "The Hangover 2" is now eying Liam Neeson, Robin Williams or Kurt Russell as a potential replacement.

While those three veteran actors sound like dandy options, we can't help but think that there are a few other celebs out there that would kick butt in a cameo so over-the-top outrageous that it'd make Mike Tyson singing look like high drama. As you may have surmised from the photo above, Justin Bieber made our "Hangover" cameo shortlist as a "Little Man"-esque version of baby Carlos. Hit the jump to see who else is on our wishlist!

Britney Spears

Nobody rocks a cameo like Britney Spears. She killed playing crazy on "How I Met Your Mother" and helped give "Glee" its best ratings ever. Cast her as a love interest for Zach Galifianakis' Alan, toss in a little casual nudity (a la Heather Graham's nursing scene in the first), and you've got yourself a winning cameo.

Arnold Schwarzenegger

Is there any movie that isn't made better by Arnold SchwarzeneggerThe Cast of "Glee"

The "Glee" kids are universally beloved and sure can grab headlines when they do anything risque (see their recent photo spread in GQ). So here's what we're thinking: Taking a cue from "Curb Your Enthusiasm," cast them as exaggerated versions of their off-screen selves -- spoiled, jaded a-holes who take their fame for granted. We're picturing some sort of drunken karaoke sing-off with Phil, Alan and co. that devolves into a bar fight... pure "Glee."

Les Grossman and Kirk Lazarus

Tom Cruise took the against-type cameo to new levels of awesomeness with his turn as foul-mouthed movie-studio exec Les Grossman in 2008's "Tropic Thunder." Perhaps Les and actor extraordinaire Kirk Lazarus (Robert Downey Jr., who stars in "Hangover 2" director Todd Phillips' "Due Date" this November) are in Bangkok to film a commercial for a Thai whiskey (yeah, their careers have fallen on hard times), but a lost weekend with Phil, Alan, Stu and Doug inspires them to make films again.

Justin Bieber

Heather Graham's stripper with a heart of gold, Jade, may not be returning for the sequel, but that doesn't mean her son "Carlos" has to be M.I.A. as well. Superimpose Bieber's face on his, and it'll be like those talking baby commercials meet the Wayans brothers' "Little Man"... but with super tween-friendly singing. Two words: comedy gold.
