Vanessa Hudgens and Austin Butler 's recent Valentine's Day vacation has taken a dramatic turn. News can confirm the Hollywood couple has sparked a criminal investigation after a vandalized rock near the Coconino National Forest showed up on Vanessa's Instagram. It all started when the High School Musical alumna shared a photo online that featured the pair's names in a heart carved into a rock. According to TMZ , there's a federal law that prohibits anyone from "damaging natural surfaces or property of the United States." Putting legal drama aside, the Hollywood pair appeared to have a nice getaway or at least until authorities got involved. The getaway also comes just weeks after Vanessa wowed audiences with her portrayal of Rizzo on the live musical Grease: Live.
