Now that Nicole Kidman has finally achieved her life's goal and given birth to a baby, we can all concentrate on why she gave it such a crappy name.

And actually it seems like there's quite a simple answer – Nicole Kidman decided to name her new daughter Sunday Rose because she really, really hates Scientology. Apparently.

You see, Nicole Kidman is a Catholic and Sundays are important to Catholics, but not important to Scientologists, and she used to be a Scientologist, so she called the baby Sunday as a sort of painfully oblique jab at Scientology. See?

Insulted, Tom Cruise has vowed to even the score by naming his next child after something that's important to Scientology, meaning that in a few years we can all say hello to little Unnecessarily Litigious Cruise or Unsettling Public Image Cruise.

Nicole Kidman isn't a bitter woman. Or at least we don't think that Nicole Kidman is a bitter woman – we haven't really been able to discern a single identifiable facial expression of hers other than 'mildly startled' since about 2004 – but if this new report is true then we might have to reverse our decision.

On Monday morning Nicole Kidman finally gave birth to her first biological baby, and we're absolutely certain that it was a moment of sheer, undiluted, life-changing joy for both her and Keith Urban. Nothing could have made the moment more perfect.

Well, except for Nicole Kidman deliberately giving the baby a name that would nark off Tom Cruise, anyway.

And that's what some are saying she did. Nicole Kidman's new baby is called Sunday Rose, which is obviously a direct insult to all Scientologists. Obviously. Don't believe us? MSNBC has spoken to a source who definitely exists and has obviously got all of the obvious facts:

“Nicole is a Catholic, and Sunday was an important religious day for her until she was involved in Scientology,” said the source. “She’s still bitter about her experience with Scientology and the fact her baby’s name could be perceived as one last jab doesn’t exactly upset her.”

Yeah! Take that, evil Scientologists! If naming a baby after a day of the week that has equal importance to every other day for them doesn't finish the religion off for good, nothing will! This is bound to hit Scientology harder than anything since the time that Halle Berry named her baby Nahla Ariela, which is an anagram of Anal Ear Hail, which is – oh, we don't know – something that Xenu invented or whatever.

Of course, there's also a report claiming that Nicole Kidman decided to call her baby Sunday Rose because Keith Urban had written a song called Sunday about the baby, and that probably sounds a bit more true.

Note to any Keith Urban fans reading – that's a brand new song called Sunday as opposed to the existing Keith Urban song Raining On Sunday, which Keith wrote before he met Nicole Kidman and was just a lonely cowboy with a dream of having a baby, naming it Sunday and getting to piss all over it whenever he liked. We don't want any confusion.

This is a joyous day, a momentous occasion that will change the world forever – it's the day when Nicole Kidman can stop whining about not having any babies.

That's right, Nicole Kidman has given birth to her baby, a little girl she's inexplicably decided to call Sunday Rose. Nicole Kidman's new daughter was born in Nashville yesterday morning, and other than that details are vague – for instance, we don't know if Sunday Rose takes after her mother and has ginger hair and an immobile face, or her father and is an alcoholic.

Best of all, we're almost completely certain that this report is 100% accurate and not an Angelina Jolie-style hoax because, well, who cares about Nicole Kidman enough to make up lies about her?

You hear that? That's the sound of Nicole Kidman not banging on about all the babies she wants. Blissful, isn't it? Because, honestly, for a while there we didn't think she'd ever stop. Any time Nicole Kidman opened her mouth over the last couple of years it was either baby this or pregnancy that or upsetting miscarriage blah blah blah. Watch The Golden Compass in reverse and you'll hear Nicole Kidman say "I want a bloody baby!" at least 17 times.

But now, nothing. That's because Nicole Kidman has given birth to her first biological baby, a little girl named Sunday Rose. Don't laugh – it's perfectly traditional for Australians to name their first-born children after something a pensioner would name a canal boat.

Anyway, Nicole Kidman gave birth to Sunday Rose yesterday morning in Nashville, and right now everything seems to be a picture of unbridled joy, as People reports:

"Husband Keith was by Nicole's side, and mother and baby are very well," said spokesman Paul Freundlich, who added that the couple were "delighted" to make the announcement. He also said the baby girl weighed 6 lbs., 7.5 oz.

Oh really? Nicole Kidman really had a baby, did she? You'll have to excuse our cynicism but we feel it's justified – throughout Nicole Kidman's pregnancy we don't think a single person even saw so much as a glimpse of her baby bump. Doesn't Nicole Kidman know that you're supposed to paint your swollen belly orange and whack it out in a magazine if you're a pregnant celebrity? That's the only way anyone ever believes you.

Anyway. We swear to god, we'd better be blogging about celebrities in the year 2026, because it's going to be a vintage year for gossip. Halle Berry's kid will turn 18, Jessica Alba's kid will turn 18, J-Lo's kids will turn 18, Christina Aguilera's kid will turn 18 and now Nicole Kidman's kid will turn 18 as well. Statistically, at least one of them is bound to grow up to be a drug-ravaged sex fiend, right?

But it probably won't be Nicole Kidman's baby. That's because Nicole has made no secret of her desire to raise her children in private on a tiny Fijian island away from the glare and bitter temptation of Hollywood.

It's also because Sunday Rose is made of 50% Keith Urban genes. If anything she'll be a booze-ravaged sex fiend.
