The former Nickelodeon star was kicked out of an L.A. Equinox gym Tuesday night for "bizarre" behavior, according to TMZ.

While Bynes was participating in a 50-minute spin class, the site says she suddenly stopped and started walking around looking for a different bike.

TMZ goes on to report that once Amanda found a different bike, she took off her top and was only wearing a "tiny black strapless push up bra ... not a sports bra."

As a result, the instructor stopped the class half way through and kicked her out.

But just yesterday, the actress told People, "I am retired as an actor. I am moving to New York to launch my career. I am going to do a fashion line. I am not talking about being arrested for DUI because I don't drink, and I don't drink and drive. It is all false."

Bynes has been charged with two counts of hit-and-run and a DUI.
