The decision to split actually came "after months of nonstop arguing," a source close to the family tells People magazine.
J.Lo has suspected for months that Marc has been unfaithful and his controlling jealous ways became too much for her to handle.
He would reportedly tell her what to wear, how to act and who to hang around, which proved to be too much for someone like J.Lo.
"They started to see life differently," the source says.
Earlier this week there were rumors that J.Lo was involved with her smoking hot ‘I’m Into You’ music video co-star William Levy, aka: the Cuban Brad Pitt. But both J.Lo and William denied the false reports.
Levy denied the rumors telling Hollyscoop: "My thoughts are with Jennifer and Marc during this very hard time. My relationship with Jennifer has been strictly professional. These alleged rumors suggesting something more personal are 100% false and inaccurate. My best wishes go out to them and their family."
Some reports suggest J.Lo is devastated by the split, and while might be going through a high-profile split, but you didn’t actually think that was going to keep Jennifer Lopez down, did you? She flew to the Ukraine yesterday to sing at a very high profile wedding, in which she got a million bucks.
Her personal life may be hurting, but nothing can keep J.Lo down!
