Okay, let's clarify here ... Lady Gaga does NOT look fat and she does NOT look like she's gained weight. At least not in these shots ...

We're simply speculating that the newly-engaged pop star might be ready to procreate with her hot fiance Taylor Kinney now that the pair have purchased a beautiful Malibu mansion and settled in.

We snapped Gaga being domestic, shopping for home interior design items in Malibu. She and Taylor were spotted out at the beach earlier this week and granted, Gaga's flow-y kaftan wasn't exactly body-con, but it sure looks like something was going on under all that silk! And it makes sense that she and Kinney would want a little monster around the house. We hope!
