The singer was tweeting about a contest related to the Billboard Music Awards when she came across a tweet from someone asking her to pay their tuition.

"Show me straight A's that I can verify w/ur school and I'll pay it. Who wants to join THAT contest?!?!," she wrote Saturday night. "Dead serious. Shld I set it up?"

She took requests for about 45 minutes, bantering back and forth with people about specifics and working out details to get the money deposited.
