Antwan “Big Boi” Patton, half of the Grammy-winning hip-hop duo OutKast, was arrested Sunday in Florida on suspicion of drug possession, according to the Miami-Dade County Corrections and Rehabilitation Department.

The substances he’s accused of having: Viagra, ecstasy pills and powder, and drug paraphernalia. Bond was set at $16,000. Circumstances of the arrest weren’t immediately available.

Relations between Big Boi and OutKast partner “Andre 3000” Benjamin had been strained over the years, even before their 2003 Speakerboxxx/The Love Below joint solo albums became a massive hit and won them three Grammys, including Album of the Year. (The pair has won six total.) However just this week, rapper Killer Mike, a frequent collaborator with OutKast, told CNN that Big Boi and Andre 3000 were back working together.

Of course, it’s too soon to know whether this arrest will seriously interrupt those plans, or merely be a minor distraction.

Most recently, Big Boi has been touring with Cee Lo Green. He also made a stop at this year’s Glastonbury Music Festival in June (see him perform “Shutterbug” there), and last year dropped his long awaited solo project Sir Lucious Left Foot: The Son of Chico Dusty, which earned an A- review from EW critic Simon Vozick-Levinson.

Big Boi’s representatives did not return calls for comment.
