Fat Joe's wife filed divorce papers after allegedly finding out that he had been cheating with Fabolous' baby momma Emily B.

Sources claim that Joe's soon-to-be ex-wife of 17 years Lorena Cartagena had suspected him of having an affair for a while, and her suspicions were only confirmed when a Terror Squad associate sent photos of them to her mobile phone.

According to Bossip, Lorena also learnt where Joe and his mistress were having sex and that he was flying her out to meet him in various locations and she even accompanied him to a Knicks game.

However, the unknown mistress was not the only woman Joe was keeping on the side. The source confirms the longtime rumours that Joe had been creeping with Emily Bustamante, who is also the baby momma of Fabolous' children and stars in Love & Hip-Hop.

Are you surprised that Joe was cheating?
