Actress Vanessa Hudgens and her boyfriend are under investigation for a social media post that has authorities wondering whether they defaced one of Arizona's protected red rocks.
Hudgens on Monday posted a purported picture on her Instagram account — since removed — of a heart with the names "Austin + Vanessa" scratched into the face of a rock.
Hudgens, 27, was with her boyfriend, actor Austin Butler, at Coconino National Forest in Sedona when they took the snaps and shared them with the hashtag #sedonadreams. Other images from their outing were left on Hudgens' account.
National Forest Service Officer Brady Smith said the problem of people carving into rocks in the picturesque landscape is a challenge.
"We have found that when one person carves something, it encourages others to carve," he said in a statement.
According to the rules of the park, defacing a "geological object," like one of the red rocks, would qualify as a Class 2 misdemeanor, which carries a maximum penalty of 6 months in jail and/or a $5,000 fine.
"The incident is currently under investigation so there is not much I can share specifically until it is completed," Smith added.
Hudgens was most recently seen in "Grease Live!" and shot to fame in the "High School Musical" movies on the Disney Channel.
