Jennifer Lopez JLOPEZMANTHONY020608_010.jpg There's nothing more enriching in life than adding a baby to your family - especially if you're Jennifer Lopez!

Advertising Age is reporting that Lopez and Marc Anthony are poised to make "between $4 million and $6 million" from People for the rights to print the first pix of Lopez' hotly-anticipated twins.

Needless to say, that's a pretty eye-opening figure - after all, even Shiloh Jolie-Pitt's first pix "only" brought in $4 million!

People, in the meantime, is hotly denying the story. "I have no comment on these particular pictures," People's managing editor Larry Hackett told Advertising Age. J-Lo's reps were similarly reluctant to comment.

Others, however, describe the deal as being pretty much done - it's just a matter of divying up the rights between People (who gets the pix domestically) and OK! (who get them internationally).

At this rate, J-Lo's gonna be earning more per baby than she makes per movie!
