You’d be hard-pressed to find a rapper in higher demand than 2 Chainz these days. With his debut solo album still months away, the charismatic Atlanta MC has logged a ton of features for the likes of Kanye West, Nicki Minaj, Young Jeezy, Big K.R.I.T. and Kreayshawn. In fact, Deuce has received so many feature calls he has decided to fall back so he can concentrate on his solo album — save for a few special requests, of course.

“Maybe a few crossover records,” 2 Chainz told MTV News on Sunday during the Atlanta stop on Drake’s Club Paradise Tour. “I just did something for Bieber; that should be interesting.”

Chainz wouldn’t tell us exactly which song he recorded with Justin Bieber, but on Tuesday night the Biebs spilled the beans over Twitter. “To celebrate the #BELIEVEtour coming … I might need to drop this #BOYFRIENDremix @2Chainz @MacMiller,” he wrote.

Mac responded with a tweet of his own, writing, “Uh oh,” helping to build anticipation for the track.

No word on when Bieber plans to drop the “Boyfriend” remix, and what it will sound like is anyone’s guess, but 2 Chainz assured us that he didn’t have to tone down his trap rap to fit in with the baby-faced 18-year-old pop star. “I’m able to express myself in different ways, so I enjoy doin’ different records like that and not just hip-hop records, so it’s cool,” he said.

After JB’s remix comes out, it may be a while before fans hear any new rap collaborations from 2 Chainz, unless they are slated for his upcoming Based on a T.R.U. Story, which drops August 14. “It’s not that I don’t have ammunition for people — it’s just that I want to focus on trying to make the album of the year,” he said confidently. “That’s something that I put out there, that’s something that I’m striving to do, and so I may do features that make sense, something that’s not in my genre, but I think I took care of all rap artists.”

2 Chainz is rolling toward his highly anticipated LP, but on Tuesday he hit an unexpected bump in the road after he was arrested in New York’s LaGuardia Airport after airport security found what they described as “brass knuckles” in the rapper’s carry-on luggage. In an exclusive interview with MTV News, 2 Chainz explained that what authorities called a weapon was actually a gold four-finger ring.

“They tried to assassinate my character, they tried to assassinate my swag,” the rapper said after he was released from jail. “It was just a negative dilemma earlier where someone misconstrued a piece of jewelry for a weapon and stuff.”
