Speculation about Angelina Jolie's pregnancy has been growing for weeks. Although the actress lost her baby weight quickly after giving birth to daughter Shiloh in late May, recently she's begun to look heavier around the tummy again.

"Angie has been looking extremely big around the mid section," says a source. "She lost a ton of weight after Shiloh was born, and now she seems to have gained it back plus some."

Another source adds , there have been other physical indicators as well, including swelling hands and bloating. Brad is thrilled, gaining a sense of fulfillment from his ever-expanding family, and hopes to have another son by next year!

Brad Pitt's rep was amused by the latest gossip: "It's so stupid. "

Angie, inspired by new movie Mighty Heart, also has plans to adopt an Indian baby to add to the already multicultural bunch. Either way, it seems that siblings Maddox, Zahara, and Shiloh will be looking forward to a new brother or sister soon!
