According to TMZ, Amanda was in a spinning class and started out riding the bike but soon after the class started her behavior got weird.  She got off her bike, moved to the mirror and took off her shirt.  She was not wearing a sports bra...she was wearing a sexy push-up bra.  

In the latest TMZ report, Amanda has been dropped by here agent, publicist and lawyer.  Wonder why? FULL STORY HERE

At least during all these crazy episodes she's getting a workout in!  I blame bath salts.
