WNBA legend Chamique Holdsclaw just pled GUILTY in that crazy attack on her ex-GF -- where she FIRED A GUN inside the woman's car -- but she won't spend a single day behind bars.
TMZ broke the story ... Holdsclaw -- one of the WNBA's all-time greats -- was arrested in Atlanta last year. Cops say the 35-year-old trailed Jennifer Lacy's car in November, then attacked it with a baseball bat and fired a gun into the backseat while Lacy was inside the vehicle.
Earlier today, Holdsclaw pled guilty to 2 counts of aggravated assault, 4 counts of criminal damage, and 1 count of illegal firearm possession.
But despite the fact she FIRED A GUN ... Holdsclaw wasn't sentenced to any jail time ... instead, she got 3 years’ probation, a $3, 000 fine ... and is not allowed to possess a gun for the next 3 years.
She's also been ordered to stay away from Lacy and complete anger management ... along with 120 hours of community service.
