And...Another Celeb Arrested!

First Tiny and T.I. were caught with a little somethin' somethin' in their car while cruising around....then Lindsay Lohan FAILED a drug test....now....BRUNO MARS!??

The "Just the Way You Are" singer was arrested in good ol' Viva Las Vegas after police found about 2.6 grams of coke on Mars!

He does look a little TOO happy in his mugshot!
