They already have five children between them from previous relationships, but rumours are rife that Mariah Carey, 45, and James Packer, 47, are set to add another bundle of joy to their blended family.
New Idea reports on Monday that the Australian billionaire and the pop diva are expecting their first child together after going public with their relationship in June.
'Mariah found out the baby news recently and they're overjoyed at the prospect of being parents,' the publication reports an 'insider' as saying.
'She adores James and it's well-known within her social circle that she would love to have children with him.'
Along with the story, the publication also ran pictures of the multi-million dollar star covered up in a white shirt and black trousers on the beach in Malibu, on August 12.
In the snaps, the curvy crooner is seen playing with her four-year-old twins, Monroe and Moroccan, while they frolicked in the shallow waters.
Mariah split with the twins' father and her husband Nick Cannon in 2014 after their marriage broke down.
A Carey-Packer baby would be the fourth in line to James' multi-billion casino empire, as he is already a father to three children with his ex-wife, Erica Baxter.
Indigo, seven, Jackson, five, and Emmanuelle, two, all reside with their mother in LA.
James and Mariah had a very public unveiling as a couple when they enjoyed a Mediterranean holiday two months ago.
They spent time together sailing around the Balearic Islands, including Ibiza and Formentera, on James's super yacht, the Arctic P.
Sources close to the songstress told TMZ the father-of-three had been 'aggressively' pursuing her and was 'obsessed' with her music after meeting at her concert in Las Vegas in April.
It makes me sad, she is obviously capable of working out, but instead she goes on constant vacations and eats alot of unhealthy stuff at restaurants
Now pregnancy rumors are starting up
lol absolutely not. Mariah still isn't done complaining about how difficult her 1st pregnancy was. for good reason bc I think she was genuinely ill and way too old
