She's still feeling the pain.

Katy Perry performed for an intimate crowd at a London venue last night, and asked for a moment of silence for the victims of the Manchester terror attack after giving an impassioned speech.

"It was hard. It was hard for you guys I know that, it was hard for me, because we all love music. You think about it and you think 'that's my friend, that's my sister, that's my brother, that's my cousin, that's the person that loves music," she told the crowd as she teared up.

"It's awful. It's awful. It's awful. And whatever you can do to help you should. And if you can't do anything to help that's fine, but what you should do is not let them win," she added.

What a beautiful moment in such tragic times.
