"Grease: Live!" star Vanessa Hudgens and model/actor boyfriend Austin Butler are under investigation for allegedly defacing Sedona Red Rocks, CNN reported.

The love birds are currently in a bit of hot water after a romantic Valentines' weekend in Arizona. Hudgens, who rose to fame by starring in Disney's 2006 hit "High School Musical," posted a now-deleted Instagram photo of their names carved into the rock surrounded by a heart.

The carving may be located in the Red Rock District of the Coconino National Forest which could be a huge problem that comes with a maximum fine of $5000 and/or six months in jail because it is against the law to damage any natural feature or other property of the United States, according to a statement issued by a Coconino National Forest spokesman, Brady Smith.

"On Monday, Feb. 15, we became aware - via medical and public reports - of an Instagram posting by Vanessa Hudgens showing a scratching or carving of a heart with two names in it on a rock that allegedly is on the Red Rock Ranger District of the Coconino National Forest," Smith stated.

Until the Forest Service Law Enforcement is completed, Smith has declined to comment more on the incident. Although it's been hard for the federal officials to catch people in the act, Hudgens, as well as his boyfriend, can possibly be in trouble for posting it on one of her social media platforms.

Smith also stated that carving of any kind affects the natural beauty of the area, and whenever one person does it, it encourages other people to carve, too.

"I 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 we try to inform people about its destructive nature," he added.
