Three Celebrities- Zero Common Sense

Which Pop starlet is denying rumors of a rehab visit-- despite the rather convincing photographs that have surfaced on the 'net?

Which NASCAR driver nearly collided with a school bus-- off the track?

Which A-list Actor's partying nearly cost him the lead role in a multi-million dollar flick?

And what do these three stars have in common?

They've just signed up for the PR campaign of the year-- a new sweepstakes contest aimed at cleaning up their image. If you thought winning a date with Tad Hamilton was exciting, wait until you hear the prize for these high school seniors: a 30 day stint as a personal assistant to a celebrity.

You can bet it will be a summer to remember.
