And two months later next thing I know
I got a text that said "I'm pregnant"
And you can almost bet she kept it
That's the reason why you left me

from T.I. (Ft. B.o.B, Kendrick Lamar & Kris Stephens) – Memories Back Then Lyrics on Rap Genius

The girl that made B.o.B. cheat on the girlfriend he had while he was rising up in fame sent him a text message saying that she was pregnant (and she was probably hoping it was his baby, since he is famous) but when he received this message, he couldn’t keep the cheating a secret anymore, so his girlfriend left him.
