The singer officially broke the news Sunday, taking to IG with a lengthy statement. She writes, "Not too much on my bestie! In all fairness, Iman and I are separated and have been for a while. To be 1000% clear, 'infidelity' ain’t one of the reasons for our departure."

She adds, "We are still the best of friends, great business partners and are one hell of a team when it comes to co-parenting our 2 beautiful children. Most importantly we are FAMILY & in the 10yrs together, 7yrs married we ain’t ever played with or about THAT."

Teyana goes on to explain that the reason she's kept this under wraps is because she's private ... and didn't feel like it was anyone's business -- a decision she's happy with as she and Iman have been able to navigate this on their terms without so much noise.

She finishes by saying ... "The only reason I’m even sharing THIS part of the chat is because the narratives are getting a little out of hand & it’s unfair to all parties involved. I hope this provided some clarity for y’all. Okay AunTey taking y’all back out the chat bye!"
