WATCH: Kevin Hart admits infidelity after blackmail attempt

Cape Town – Kevin Hart posted an emotional video on Instagram on Saturday in which he apologises to his wife and kids for his "mistakes".

According to TMZ, Kevin’s apology comes after a failed extortion attempt over a sexually suggestive video.

According to sources who have seen the three clips, it’s not a sex tape, but looks like a prelude to sex. And in the clip that’s reportedly the most suggestive, Kevin can’t actually be seen.
