Faith Evans — a singer who was married to the Notorious B.I.G. — has been sentenced to 36 months of probation after copping a plea in her DUI case.

Evans — who was popped in L.A. back in August — was facing 2 counts of DUI … but worked out a deal with prosecutors in which she agreed to plead “no contest” to the lesser charge of reckless driving instead.

Besides the probation, Evans must also pay $300 in fines, complete a 3-month alcohol program and must not drive with any measurable amount of alcohol in her system.
