Beyonce Knowles is finally in labor!

The nine-months' pregnant singer is said to have checked into Lenox Hill Hospital under the pseudonym "Ingrid Jackson," a NY Daily News report claims.

Beyonce and her rapper hubby Jay-Z have rented out the hospital's entire fourth floor for $1.3 million, the paper reports.

Hospital workers placed tape over security cameras and are requiring their employees to turn over cell phones when they clock in, according to the report.

The 30-year-old singer was last seen Thursday as she left a Manhattan apartment building. The couple are said to have celebrated New Year's Eve at a Brooklyn restaurant.

Superstar couple Beyonce and Jay-Z attended the early performance of Michael Jackson THE IMMORTAL World Tour in Las Vegas Saturday at the Mandalay Bay Events Center.

The radiantly-pregnant Beyonce wore a leopard print dress with an embellished neckline and sported gold high heels. Following the performance, the couple visited the backstage area to meet some of the show’s 64 artists.

Beyonce and Jay-Z were in Vegas for the weekend for Jay-Z’s Friday night concert with Kanye West.

Kourtney Kardashian has announced she's pregnant, after X17online posted photos of her baby bump Monday.

In fact, our readers did a good job at guessing -- our poll had 52% of you saying you believed Kourt was with child, while only 21% thought her "clothes were just baggy." 26% of you said you weren't sure -- but we were!

The actress shared the news with Us Weekly, telling the mag she's nine weeks along. The E! reality star, 32, took a pregnancy test about five weeks ago and woke up boyfriend Scott Disick at 7am to break the news to him.

Disick says, "It wasn't like we weren't trying. We kind of just said, 'If it's meant to be, it'll be.'"

This will be baby number two for the unmarried couple. The pair's son Mason is 2 years old.

Seriously, we've always been fans of Jennifer Garner, but this third-time mom is becoming more-and-more our favorite as her pregnancy wears on!

Between raising her two daughters Violet and Seraphina, holding down her acting jobs, and supporting hubby Ben Affleck while he's alternately in town and out of town shooting his new movie Argo on location, this lady's really handling all her roles with grace and style!

We know you're pregnant, January! And yes, we know a woman's belly grows when there's a baby inside. So why hide it?!

Ms. Jones looks fabulous and has nothing to hide ... except the identity of her baby daddy! Come one already, who's the daddy?!

Pregnant pretties Tori Spelling and Jennifer Garner are focusing on the important things in life ... and that does NOT include makeup (take notes, Kim K)!

The glowing girls stepped out au naturel Friday to run their respective errands. We love seeing these ladies in their natural state, dressed down, looking real.

Speaking of real ... things must be getting "real" for Ms. Spelling right about now. It's 100 degrees in Los Angeles and the mother of two is due with number three in a couple short months. Hang in there, Tori!

IF we had a countdown clock on this website, we imagine we'd use it to count down the days, hours, minutes and seconds until Selma Blair is due to give birth. And we imagine it would have been at 00:00:00:00 for at least a week now ...

The actress dressed up for an event at the Hotel Sofitel in Beverly Hills Friday night, looking amazingly beautiful but perhaps just a teensy bit tired of being pregnant!

Jessica Alba and hubby Cash Warren are sure to get lots of 2-on-1 time with daughter Honor before their new baby arrives. The adorable threesome is always at the park together on the weekends and yesterday was no exception -- the group headed to sunny Malibu for some lunch and some monkey bars!
