Popstar Selena Gomez took everyone in Las Vegas by surprise last night, when she arrived onstage sporting a ‘Justin’ tatoo on her wrist.

However, the mark, which featured her boyfriend Justin Bieber’s first name with a heart underneath it, seemed to be written in magic marker.

Later, Gomez’s representative confirmed that it wasn’t a permanent marking and was in fact a marker.
