Now that Lindsay Lohan has been behaving herself it seems as if the open slot for my favorite celebrity hot mess will be filled by Amanda Bynes. The former Disney star actress was spotted driving around aimlessly for hours on Tuesday by the paparazzi.

With a suspended license. And smoking out of a marijuana pipe.

Bynes began her journey at Baja Fresh in the San Fernando Valley where she smoked from the pipe and wolfed down tacos in the parking lot. Obviously she had a severe case of the munchies.

Bynes headed over to a spa where she spent three hours inside before taking another leisurely drive the neighborhood.

The actress was tailed by the paps who witnessed her driving around aimlessly, cutting off other drivers and violating various traffic laws. Bynes pulled into a Home Depot parking lot and took another few pulls before heading inside to buy s few light bulbs.

Bynes had her license suspended back in August stemming from a DUI bust back in April where she side-swipped a police car. During that incident, she insisted she never drank alcohol in her life and took to twitter to ask President Obama to fire the arresting officers.

Take a look at the inside of her car. With trash strewn everywhere, a blanket in the window, stains on the seats, empty bottles, dog hair and even ‘tobacco leaf remnants in the cup holder. Just a waste of a BMW.

Bynes, who is worth a reported $8 million and can certainly afford to hire a driver for these leisurely joyrides, has been charged with a couple hit-and-runs and is expected to be back in court in November.

Bynes gets my vote for best celebrity hot mess of the month.
