So it wasn't just an Urban legend.
Nicole Kidman and hubby Keith Urban are expecting their first child together, E! Online has confirmed.
"The couple are thrilled," Kidman's U.S.-based rep Catherine Olim said.
As recently as last week the actress' camp was adamantly denying reports that Kidman was pregnant.
But where there's smoke, there's usually a bun in the oven. The New York Post's Page Six reported Monday that Kidman had dropped out of the upcoming period drama The Reader, further fueling speculation that the Golden Compass star was taking it easy for a reason.
The role of a woman of a certain age who has an affair with a teenage boy in post-World War II Germany has since been handed over to Kate Winslet, the filmmakers' first choice before Kidman was cast.
Winslet originally turned the part down because the initial production schedule conflicted with her work on Revolutionary Road, costarring Leonardo DiCaprio, which will be out later this year. A hiatus was built into the schedule after production on Baz Luhrmann's Australia kept Kidman busy longer than expected.
A source also told the Post that Kidman's photo shoot for Vanity Fair's annual Hollywood issue had to be pushed up, "because the costumes she's set to wear won't fit her much longer."
The 40-year-old Oscar winner has two adopted children with ex Tom Cruise. This will be the first child for Urban, who swapped vows with Kidman in June 2006.
Kidman revealed to Vanity Fair last summer that she suffered two miscarriages while married to Cruise, prompting their decision to adopt.
"From the minute Tom and I were married, I wanted to have babies," the actress said. "And we lost a baby early on, so that was really very traumatic. And that's when we would adopt Bella."
Daughter Isabella is now 15, and their son Connor is 12.
Kidman and Cruise split up in 2001 and she was briefly engaged to Lenny Kravitz before meeting Urban in 2005.
She and Urban, a native New Zealander, tied the knot in a Catholic chapel near her family's home in Sydney, Australia. A lavish reception attended by 230 of their nearest and dearest followed the clifftop nuptials. Longtime Kidman pals Russell Crowe, Hugh Jackman and Baz Luhrmann were among the revelers.
In September, the newlyweds purchased a farm near Leipers Fork, Tennessee, about 30 minutes away from Nashville, possibly with the pitter-patter of little feet in mind.
"I'm yearning to have one," she told Vanity Fair about the couple's plans for a new addition. "I think I would be very sad if I wasn't able to have a baby. Keith knows I want one, and he has been getting there slowly."
Urban, who entered rehab four months after the duo said "I do," has credited Kidman with helping him get his life back on track.
"They say grief makes hearts and closer bonds than joy ever can," the country-music star said last year. "We've gotten through a lot and she's been extraordinary."
