The forth celebrity with a sexy bikini body is Vanessa Hudgens.
The High School Musical star definitely has one of the fittest body and strongest abs among the celebrities.
She has been very often spotted coming or going to the gym, so we know that she is working hard for that body of hers!
The actress dated the #3 on the hottest abs in Hollywood and former co-star Zac Efron, from 2005 until 2010.
They both seem to have gotten hotter after they broke up, could that be that look-what-you-missed-out-on move?
She is a wrestling fan ->
