Tyrese is off the pills that were making him crazy.

But crazy things keep happening to him.

The R&B singer and actor was closing his set at the Valentine's Love Jam in Detroit when an overenthusiastic fan ran up on stage. 

She got a little too close to Ty and he responded with a stiff shove.

Although it was more-or-less self-defense, it looked like Tyrese felt pretty guilty about putting such pushing power into a lady.

Maybe he was spooked because he thought The Rock had sent some shooters.
