Is Nicole Kidman expecting a "miracle baby" at 49 with husband Keith Urban? That's what OK! magazine reports. Despite her age, Kidman and her musician husband are allegedly trying for a third baby, but her pals think she's already pregnant.

"When she jumped on stage to sing and dance with him... that's when a few friends thought, 'She's glowing. Something is up,' " reveals an insider, who supposedly attended a New Year's Eve party with the "Lion" actress and the Australian singer.

The couple was said to have marriage problems before the supposed baby news surfaced, as stated in the cover of the tabloid, "The decision that saved Nicole and Keith from the brink of divorce." It went on purporting that Kidman had been "furious" after allegedly finding out that her husband had an affair with singer Kelsea Ballerini, who's the opening act on his tour two years ago.

"It was bad between them for a while after that," said the so-called insider, who further claimed that a baby has solved their alleged problems.

However, a rep for Kidman has shot down all the above claims, telling Gossip Cop that the "Paddington" actress is "absolutely" not pregnant. Furthermore, Kidman is not planning to have a baby to save her marriage to Urban when they don't even have marital problems.
