Keyshia Cole puts her estranged husband on blast on instagram

Just last week, everything was good with singer Keyshia Cole and her estranged basketball player husband Daniel Gibson. In fact they went public with their plans to give their marriage another try. Daniel shared this pic above of Keyshia and himself at Keyshia's reality show premiere party and praised his wife.

Well, it looks like that's over with. Last night Keyshia posted screen shots from Daniel's phone where she caught him chatting with a video model on the set of his new video.

I see she's very hurt by this. But why post this on social media?
