Nick Cannon Speaks On Involvement in Amber Rose Divorce

For those of us (yes us!) that were speculating if Nick Cannon had any involvement in Amber Rose and Wiz Khalifa breakup, well I have an update.

Sources close to Nick tell TMZ ... Nick and Amber, who just recently got into business together, have kept things strictly professional. Nick insists that "NOTHING happened in the cheating department".

Nick claims he only learned about Amber's domestic problems through her lawyers last week when he signed her on as a client. That's when Nick says he found out her marriage was on the rocks and only then did the two share break-up stories.

Multiple sources informs TMZ that Wiz and Amber are putting blame on the other of cheating.
