OutKast's Antwan "Big Boi" Patton was arrested in Miami on Sunday for drug possession.

The 36-year-old rapper allegedly had ecstasy, MDMA powder and Viagra at the time of his arrest, according to the Miami-Dade County Corrections Department.

Patton, who commonly goes by his stage name "Big Boi," was met with customs and border patrol dogs as he was getting off a cruise ship, TMZ reports. He was officially booked at 1:35 p.m., held at a $16,000 bond and released late Sunday afternoon.

"While Big Boi was traveling with his group and friends, a small amount of contraband was found in the collective luggage . . . I am confident when the entire facts are aired Big Boi will be completely exonerated," his attorney Daniel Kane said in a statement to CNN.

OutKast, made up of Big Boi and André "3000" Benjamin, first rose to fame in 2003, thanks to their Grammy Award-winning hit "Hey Ya!" from their double album "Spearkboxxx/The Love Below."

The group has sold more than 25 million albums since forming in 1992. In 2001, OutKast released a greatest hits album called "Big Boi and Dre Present . . . OutKast."

In 2010, Big Boi released a solo album called "Sir Luscious Left Foot: The Son of Chico Dusty," producing hits like "Shutterbug" and "General Patton."

The Miami arrest comes just days after rapper Killer Mike, a regular OutKast collaborator, confirmed to CNN that the duo had plans to make a new OutKast album.

Earlier this summer, Big Boi appeared at the Glastonbury Music Festival, promoting his solo project, and most recently the rapper has been touring with Cee Lo Green.
