Beyonce & Jay-Z

Kim Kardashian has figured out the best perk of dating Kanye West ... she gets to kick it with the one and only Beyonce.

While their respective men performed on stage, Kim and Beyonce were spotted hanging out enjoying Kanye and Jay-Z's concert in England this weekend.

An eyewitness at the show tells us the new besties "danced and sang all night together" and even made their way to the craziness of the mosh pit at the Birmingham stop of the Watch the Throne tour.

Michelle Williams wants to make one thing clear -- babysitting for Beyonce's baby girl is just a part-time gig ... because she's not the only Destiny's Child singer doing diaper duty for Blue Ivy.

Last night in NYC, Michelle revealed Kelly Rowland also pulled a shift watching B.I. in Beyonce's hotel suite ... during B's concert in Atlantic City last weekend.

In the middle of the show, Beyonce thanked Michelle for babysitting -- but Michelle 'fessed up to us she had some help ... and even got to go downstairs to see some of the show.

Jay-Z and Beyonce carried a heavily bundled baby Blue Ivy out into the world for the first time ... hitting up Sant Ambroeus in the West Village for a little lunch today.

This is what the heir to a hip-hop fortune looks like ...

Beyonce and Jay Z have finally posted photos of Blue Ivy Carter .. which appear to have been taken at their pimped out suite at Lenox Hill Hospital in NYC.

The Carters posted a note along with the pics which reads, "We welcome you to share in our joy."

Blue Ivy was born on January 7th.

It appears Beyonce color coordinated for the shoot with Blue Ivy ... check out her blue fingernail polish.

Beyonce's new baby Blue Ivy Carter is the devil incarnate -- this according to some heartless vandal who defaced the sign in front of a North Carolina church yesterday ... writing, "Beyonce had her baby. Satan is on Earth."

The pastor at Beulah Hill Baptist Church in West End, NC tells TMZ, he discovered the vandalism yesterday after receiving numerous complaints from locals -- and removed it immediately.

The pastor insists, the church had nothing to do with the apocalyptic message ... it was simply the victim in a random act of mischief.

Blue -- Satan? No. Illuminati? ALMOST DEFINITELY.

Beyonce says she gave birth to Blue Ivy the same way women have been giving birth for thousands of years ... naturally -- insisting she did NOT get a C-section.

There were reports the singer birthed Blue with the help of a scalpel -- but Bey and Jay-Z released a joint statement moments ago, claiming, Blue "was delivered naturally at a healthy 7 lbs and it was the best experience of both of our lives."

Beyonce and Jay-Z did NOT pay $1.3 million so the Destiny's Child singer could give birth to Blue Ivy in a sealed off private floor ... this according to the hospital.

A rep for Lenox Hill Hospital just released a statement, claiming, "The suggestion that the couple paid $1.3 million to rent an entire maternity floor is simply not true."

The rep adds, "The family is housed in an executive suite at the hospital and is being billed the standard rate for those accommodations."

According to the rep, "The family does have its own security detail on site. However, the hospital has been and continues to be in control of managing all security at the facility. We have made every effort to ensure minimal disruption to other families experiencing the births of their own children over the past three days."

Jay-Z just revealed ... Beyonce suffered a miscarriage before conceiving their daughter Blue Ivy.

The rapper dropped the bombshell in his newest song "Glory" -- which he released today in honor of Blue Ivy's birth this weekend -- rapping, "Last time the miscarriage was so tragic/We was afraid you'd disappear/But nah baby you magic."

The song was produced by Pharrell -- and even includes an audio sample of Blue Ivy crying just moments after she was born.

Beyonce finally popped, giving birth to a baby girl named Blue Ivy Carter in New York City on Saturday

Proud dad Jay-Z, real name Shawn Carter, was at the hospital where Beyonce reportedly birthed Ivy by c-section -- and shortly after her arrival ... J & B's famous friends started sending out birth announcements on the Internet.

Rihanna tweeted, "Welcome to the world princess Carter! Love Aunty Rih"

Hip-hop mogul Russell Simmons also took to Twitter, saying ... "congrats to my good friends Beyonce and Jay-Z."

Beyonce famously announced her pregnancy on stage at the MTV Video Music Awards back in August.

Beyonce and her alleged baby bump (kidding!) went out for a stroll in New York City yesterday.

We know it sounds ridiculous ... but the Internet is buzzing with rumors that Beyonce is NOT really pregnant and she's wearing a fake stomach in an elaborate cover-up. Now, a controversial new video is fueling the fire.

Beyonce appeared on an Australian TV show this weekend called "Sunday Night" -- wearing a tight red dress that accentuated her baby bump.

But when B sits down in her chair, her bump appears to collapse inward, leading many to believe it's not B's real bump after all ... but a prosthetic device intended to deceive.

So why would B fake preggo? There are rumors that she has hired a surrogate mother to carry the kid, so she won't have to put her body through the strains of pregnancy.

But color us skeptical -- because last month, Bey bared all during a vacation in Croatia with Jay-Z ... revealing what looks like a totally legit baby bump.

We called B's camp for comment -- but we haven't heard back yet.

So, we gotta ask ...

After revealing she was pregnant on the VMAs last week, Beyonce -- who just turned 30 -- showed off her growing bare baby bump while vacationing with Jay-Z in Croatia on Tuesday.

Her destiny's child is in there.

Beyonce celebrated her 30th birthday just like every other expectant mom -- ballin' her face off on a massive yacht in Venice, Italy!

B and Jay-Z held court aboard the super luxurious yacht "Odessa" ... for her big 3-0 celebration -- which included visits from celeb pals Gwyneth Paltrow and Erykah Badu.

Beyonce was seen on-deck checking out her not-yet-visible baby bump.

Beyonce just showed up to the MTV VMAs with a very special guest -- HER FETUS.

Rumors have been swirling about B having a bun in the oven for weeks ... but tonight she confirmed the buzz by showing off her baby bump on the red carpet.

With Beyonce as the mom ... and Jay-Z as the dad -- one thing's for sure ... THAT KID IS GONNA BE RICH!!!!
