J. Lo's Watching You, Marc!

Are all those breakup rumors true?

Despite the fact that they've been snapped looking all lovey-dovey in LA since J. Lo was spotted without her wedding ring, we can't help but wonder if there's still trouble in the Anthony-Lopez house.

Now Page Six reports that J. Lo is so distrustful of her hubby that she sent her assistant to spy on him during his tour while she stayed home with the twins.

The source told P6, "She wanted reports back so he didn't cheat on her."

So did she get the info she wanted?
