Vanessa Hudgens and Austin Butler Incident Under Investigation Over Rock Carving

Actress Vanessa Hudgens and boyfriend Austin Butler could be in trouble following a romantic getaway to Arizona.

The couple allegedly did a little rock carving — their names inside a heart — while visiting Coconino's National Forest and posted a picture fo the art work on Instagram. The incident is now under investigation.

The post has since been deleted, Brady Smith of the U.S. Forest Service tells People in a statement, "This incident is currently under investigation, so there is not much we can share specifically. However, we can say that the issue of people carving their names and other things in rocks in the Sedona and surrounding area is always a challenge we face and try to educate people about. We have found that when one person carves something, it encourages others to carve."

He continued, "Carving of any kind affects the natural beauty of the area and it is something that is prohibited under Title 36 of CFR 261.9 (a) 'Damaging any natural feature or other property of the United State.'"
