B.o.B. is well known for his cross-genre collaboration with Hayley Williams of Paramore on the hit song “Airplanes.” And it looks like that won’t be his last. In a joint interview with T.I. for Fuse at South by Southwest (SXSW), the question was put to B.o.B. about the rumors that Taylor Swift would be appearing on his new album Strange Clouds. B.o.B. declined to confirm or deny, but T.I. stepped in and confirmed Swift is on a track saying, “I can. I heard it.” And with T.I.’s okay, the details started pouring out.

T.I. gave Swift props, saying, “Taylor’s [got] extended hustle game. She’s a part of the crew, she just don’t have her dog tags yet.” B.o.B. confirmed that they hooked up when, “She came to Atlanta and she hit up [T.I.'s] Grand Hustle [crew].” It’s not Swift’s first time around the crew. She collaborated with T.I., getting him to perform the hook on Rihanna’s “Live Your Life” with Swift when the Fearless tour hit Atlantic last October.

B.o.B. looks to be gearing up for his own hot summer, with a new album on the horizon and this teaser of “So Good” before the video hits on March 21.
