This week in pop culture, one celebrity surprised gossip readers with baby news, and gossip readers surprised a celebrity with baby news! On Jan. 17, People Magazine reported that Nicole Kidman and her husband, Keith Urban, are the parents of a new baby girl. Faith Margaret Kidman Urban was born Dec. 28 at The Women's Hospital at Centennial in Nashville. Faith, the biological daughter of Kidman and Urban, was born through a gestational carrier. Kidman and Urban kept the pregnancy and birth a complete secret, even keeping the matter quiet at the Golden Globe Awards."Our family is truly blessed and just so thankful to have been given the gift of baby Faith Margaret," a rep for the family told People Magazine. "No words can adequately convey the incredible gratitude that we feel for everyone who was so supportive throughout this process, in particular our gestational carrier." Faith is the second daughter for Kidman and Urban, who are also parents to Sunday Rose, 3 years old. Kidman is also the adoptive mother to two children, Isabella and Connor, with ex-husband Tom Cruise.

While Kidman and Urban were busy pulling the wool over all our eyes, recently married Hilary Duff was surprised to learn that she was pregnant this week. Her news source? Star Magazine! On Wednesday, Star Magazine reported that Duff and her NHL-star husband Mike Comrie were expecting their first baby. The magazine claimed that Duff was seven months pregnant. A "close friend" of Duff told Star that "they weren't actively trying to conceive but agreed that if it happened, it happened. . They're ecstatic!"

The news of her pregnancy caught Hilary herself completely off-guard. Responding to hundreds of Twitter posts congratulating her on the pregnancy, Duff tweeted, "Wow what a way to wake up and find out your [sic] pregs! It's just a rumor guys! Not true. But thanks for all the good wishes!" Duff's rep told JustJared.com that the actress is absolutely "not pregnant." "I'm only 23, so give me a little bit of time. Come on people!" Duff tweeted later on Wednesday.

Star's preview article (advertising the "exclusive feature" in the magazine on shelves) reported (truthfully) that Duff had been very candid about wanting a big family, saying that she and Comrie were "really excited about having little ones of their own." While there's no doubt that Duff will be an adorable pregnant celeb and a great mom, let's not go putting babies in her without letting her know!
