The mixed jury retired for 58 minutes and returned a five-to-two verdict on both counts.
He was, however, found not guilty of rape.
High Court Judge Vivene Harris then ordered the former Special Sergeant remanded until March 13, when he is to be sentenced.
The court heard that in 2012, the accused met the complainant at a party in the Corporate Area.
He offered her a ride, and during the journey, he reportedly made sexual advances which were spurned.
The accused allegedly held her and sexually assaulted her.
A report was made to the police, and following an investigation, he was arrested and charged with buggery and rape.
He was on bail prior to the guilty verdict.
In November 2010 the well publicized case was reported on in the Star News:
After completing a sentence for rape in 2008, deejay Zebra was yesterday again locked away for 30 years' hard labour for another sex-related crime.
The deejay, whose real name is Garfield Vassell, was sentenced by Justice Evan Brown in the St Catherine Circuit Court.
Justice Brown outlined that for buggery, Vassell should serve 10 years and 20 years for carnal abuse.
The entertainer, who was represented by attorney-at-law Everton Dewar, was found guilty on Tuesday by a jury which retired for less than an hour. He was found guilty of carnal abuse and buggery.
The Crown led evidence that the entertainer sexually assaulted the teenage daughter of his girlfriend.
It is said that the child had to run away from home and related her ordeal to a senior relative who reported the matter to the police.
The deejay, who is known for songs such as Redder Than Red and Rupert, was held in June of last year after eluding the police for four months. He had been released in 2008 on rape charges, after serving six years behind bars.
