Vanessa Hudgens under investigation for allegedly defacing Sedona Red Rock

Vanessa Hudgens and Boyfriend Austin Butler Are Under Investigation For Alleged Etching

Vanessa Hudgens is between a rock and a hard place after an alleged act of love has brought her under fire.

The 27-year-old actress and her 24-year-old boyfriend, Austin Butler, allegedly carved their names in a heart into a rock formation in Sedona, Arizona over Valentine's Day weekend, but the gesture might have broken a federal law.
