Police found the married couple brawling outside of the house while she was allegedly drunk around 3:45am and now, she's landed a spot in jail for the next 93 days.
Da Band singer Sara Stokes -- who's been in and out of trouble since the group's heyday -- is in jail after a knock-down-drag-out brawl with her husband.
Cops tell us ... they were called to Stokes' home July 21st at 3:45 A.M. ... and found her and hubby Tony outside -- fighting on the ground. They say Stokes was drunk.
Stokes was arrested and charged with domestic violence. And as if things weren't bad enough ... she's now in hot water because the arrest has triggered a probation violation for a prior DV incident -- also involving her husband. So she'll be spending the next 93 days in the pokey for that.
Stokes has had other run-ins with the law since Da Band hit it big in 2002 on "Making the Band 2." She was arrested in 2009 for stabbing her husband ... and got 3 years probation in a plea deal.
