She's currently getting race reviews for her performance in the London Play Photograph 51, but the newest batch of rumors are suggesting that Nicole Kidman may have a very different reason for smiling.  

Keith Urban Supports Nicole Kidman At 'Photograph 51'

According to reports, the 48-year-old actress and her husband, American Idol judge and country star Keith Urban, are expecting a third child together-this time a son. A smiling Kidman graces the cover of Australia's New Idea magazine, where she appears to be clutching her belly-which has started off the firestorm of reports.  

Kidman and Urban married in 2006 and have two daughters together, Sunday Rose and Faith Margaret.

However, before fans begin inundating the couple with well-wishes, it is likely that the reports are false. Gossip Cop recently shot down rumors that Urban found a secret sex diary Kidman was keeping, which allegedly did detail her wish to get pregnant one last time and for it to be a boy.  

In addition to that rumor, the alleged sex diary (which was reported as being extremely false), the journals allegedly detailed her relationships in the past with both Lenny Kravitz and Russell Crowe, as well as her first marriage to Tom Cruise, which she supposedly called "the worst time of her life," and that she felt she had "missed out" on her kids Connor and Isabella's childhoods because they had lived with their father.  

The report also claimed that Kidman had expressed fear Urban would cheat on her with Jennifer Lopez because the two exhibited flirty behavior.  

However, the reports have all been proven false-meaning Kidman is likely not pregnant.
