Mayers is the partner of global megastar Rihanna, who attended much of the trial and brought their two toddler sons to closing arguments.
Rapper A$AP Rocky has been found not guilty of felony assault, following a high profile trial in Los Angeles.
A jury returned the verdict on Tuesday afternoon after deliberating for just three hours.
On the eve of trial, Mayers turned down a prosecution offer of just six months in jail, along with probation and other conditions, if he would plead guilty to one count.
The defense argued that Mayers fired blanks from a prop gun that he picked up from a music video set, bringing in two of the rapper’s inner circle to attest to that.
