"I'm so sorry, you would do this for me and I would do this for you."

We've all had the horror of either having something on our face or in our teeth for a prolonged period of time and just wished someone had told us about it earlier and Emma Watson, it turns out, will not stand for that happening to anyone.

The 'Beauty and the Beast' star and feminist champion interrupted her own interview with Movistar Spain after noticing her interviewer had ink from a pen on her chin and, being a normal human being that has clearly been the victim of rogue ink/lint/other face attractive substances before, took it upon herself to remove it.

"You've got pen on your chin, and you're going to be so sad when you see this, and I just have to do this for you," she said, leaning over and wiping away the ink from beneath her chin. "I'm sorry, I know what it's like to have something on your face."

Watson then called in her own makeup artist to touch up the affected spot before allowing the interview to resume.

Emma Watson - soundest Disney princess ever.
