Oh Boi! Rhyming ATLien Big Boi — one-half of the Grammy-winning rap duo OutKast — has been arrested in Miami on charges of drug possession.

Miami-Dade County cops caught the 36-year-old hip-hopster transporting ecstasy tablets, Viagra (for which he didn’t have a prescription), and MDMA, the main ingredient in Ecstasy, as he exited a cruise ship. The rapper, whose real name is Antwan Patton, was booked into jail at 1:35 PM EST Sunday and slapped with three counts of possession of a controlled substance and one count of possession of drug paraphernalia, according to the Miami-Dade County Corrections Department. He’s being held on $16,000 bond.

Big Boi is best known as half of the groundbreaking group, which includes Andre 3000. The Atlanta-based group won six Grammys and churned out six platinum-plus albums, including their 2004 smash Speakerboxxx/The Love Below, which sold over 10 million copies.

Word is Big Boi owes $55,727 and has been under an Internal Revenue Service-induced lien since June.

Andre Benjamin — aka Andre 3000 of the Grammy-winnning hip-hop duo Outkast– was arrested outside his hometown of Atlanta at about 12:30 a.m. Saturday after he was clocked doing 109 mph in a 65 mph zone in his Porsche.

According to TMZ.com, Andre, 33, was taken to the Henry County Jail where he was booked and had his mugshot taken. He posted $1,200 bail and was later released.

Mary J. Blige joins Big Boi in the new video for the rapper’s single “Sumthin’ Gotta Give.”

Big Boi and Mary J. Blige have teamed up for the track “Something’s Gotta Give,” to be featured on Big Boi’s upcoming solo album.

OutKast star Big Boi has revealed plans to release his debut solo LP in early 2008.

“I want all the stuff to be ’08, everything to be brand new. I’m going to put 12 songs on [Sir Luscious Left Foot], I’m finished with like nine right now. Production is by Organized Noize,” the rapper told Vibe Magazine.
