Zac Efron stinks?!

In our 'ewwww' story of the week, an insider on the set of High School Musical 3 has revealed that hottie Zac Efron doesn't like to shower - even when he's sweaty and stinky after exercising!

"Zac isn't a big fan of showering. It's so gross, because Zac loves to work out and plays basketball all the time - and then goes days without showering... When he gets lazy, he likes to clean himself with baby wipes!" revealed the source.

Ick! There's no denying Zac is SHRN, but he must be pretty smelly, too! We wonder what GF Vanessa Hudgens thinks of his grossness?
