Bruno Mars' plea for his cocaine arrest in Las Vegas last September was accepted by a Clark County court today. He has to return to court a week from Monday (aw, Valentine's Day!), and if he keeps his nose clean over the next 12 months and does 200 hours of community service, his arrest will be wiped right off the record. Here's hoping he walks the straight and narrow (and he keeps using whatever product he's been using in his hair, because it looks great).
