Perhaps Whitney said it best when she proudly professed that “Crack Is Whack!” in her infamous 2002 interview with Diane Sawyer.

No one needs to hear those words right now more than fallen actress Maia Campbell. The girl is sitting in a raggedy Monte Carlo eating Lays chips and spazzin….Somebody signal the Prayer Circle because we can’t tell if its crack, meth, or sherm!

The chocolate beauty — once known as the daughter of late novelist Bebe Moore Campbell (died of brain cancer in 2006) and star of LL Cool J’s ’90s TV hit In the House — was recently recorded on the streets of Los Angeles high as Cootie Brown, cursing folk out, and confessing to selling vag for rocks.

Oh boy…

Maia is rumored to be bipolar and off her meds — which is believable because she seems very off her rocker. The former actress, who has a young daughter named Elizabeth, is reportedly prostituting herself to support her drug habit.

The footage is the latest in a string of troubles for the emotionally-troubled actress, who was accused of stealing a friend’s car in 2007.
