Check out what B.o.B. has to say on it:
HipHopDX: Talk a bit about The Man and The Martian album that you and T.I. are reportedly working on...
B.o.B.: The Man and The Martian is something we’re talking about, an idea that we’re playing with. We just kinda wanna let it happen and record as we see fit.
DX: That idea’s kind of crazy though.
B.o.B.: Mars and Earth aren’t too far apart. [Laughs]
DX: So you’re Mars.
B.o.B.: I mean, they’re interchangeable.
DX: Your styles are vastly different from one another. Will the album be you and T.I. playing off of each other or more of you meeting in the middle?
B.o.B.: I feel like when me and [T.I.] get in the studio, we can organically make music and Tip actually co-produced one of the songs on my [The Adventures of Bobby Ray] album, “Fifth Dimension.” A lot of people don’t even know that, so I have a lot of confidence that we’ll show people just how close Earth and Mars are.
DX: When did you start talking about doing a collaborative album?
B.o.B.: It’s been something that’s always been in the air, but it’s kinda has to materialize at its own pace but I would be prepared to see some music coming from The Man and The Martian.SOURCE
