Lindsay Lohan’s girlfriend has taken time out of her busy schedule as a celebrity mixmaster to brand one-hit wonder Coolio an “idiot” after the star was arrested on suspicion of drug possession on Friday.

Last Friday, the rapper-turned-reality TV star was detained by police at Los Angeles’ LAX airport when security staff allegedly found crack cocaine on him. Coolio was booked on drug charges and released on $10,000 bail.

“The thing that baffles me most is the fact that you can’t even smoke on planes anyway… if you’re gonna be an idiot and do drugs – I guess I should just stop there – if you’re dumb enough to do drugs then you’re probably not thinking about much else….” DJ Samantha Ronson wrote on her Myspace page on Monday.
