Mariah Carey may have a bun in the oven. Rumor has it, the pop/R&B diva and her boyfriend James Packer are expecting their first child together, after going public with their romance in June. New Idea (via Daily Mail) cites a source as saying, "Mariah found out the baby news recently and they're overjoyed at the prospects of being parents."

Should the baby news be true, it will be a third child for Carey who already has four-year-old twins Monroe and Moroccan, from her marriage with Nick Cannon. Packer, meanwhile, is already a father of three with his ex-wife Erica Baxter.

The couple recently enjoyed a holiday in Malibu. In some pictures obtained by the Australian magazine, the 45-year-old singer donned a white shirt and black trousers while walking on the sandy beach on August 12. She was also seen playing with Monroe and Moroccan while they frolicked in the water.

Carey and Packer dating rumors first emerged in June when the two were photographed strolling the street in Capri, Italy hand-in-hand. They continued their trip by heading to Jerusalem, Israel, where they visited the Western Wall.

Neither Carey nor her representative has commented on the pregnancy rumors.
