Honeymoon over for J.Lo and Marc?

The union of Jennifer Lopez and Marc Anthony has always been something of a mystery. Since quietly marrying in 2004, they’ve largely kept mum about their relationship. Now comes a report in the New York Post that cracks may have begun to appear in the surface of their domestic bliss.

One source claims to have witnessed the couple fighting on New Year’s Eve, while another told the paper of a spat on Super Bowl Sunday — and a painful incident at a recent Miami album listening party.
