J.Lo to People: Don't Call Me Dat!!

TMZ has learned not only has Jennifer Lopez sold her baby pics to People mag for a cool $6 mil -- she got the mag to agree to stop calling her J.Lo!

A source tells TMZ J.Lo made the deal and threw in the moniker clause as well. We're also told J.Lo instructed People, in addition to the loot and the name thing, that her hubby, Annie Leibovitz wannabe Marc Anthony, has to be the one to shoot the photos.

Reps for mom were mum.

UPDATE: A rep for People tells us, "This is absurd, but thanks for the additional publicity on the photos."
