(Yahoo!) - Kim Kardashian might be busy celebrating her 33rd birthday Monday, but all eyes were on her delivery room drama Sunday night.

In a new promo for next week's installment of "Keeping up with the Kardashians" on E!, we finally get to see just how crazy the moments before the star gave birth to North West really were. The 30-second clip shows Khloé on the phone with her older sister, with a panicked Kim saying, "I have to deliver this baby right now!"

Not only is the world buzzing about just how much of the emergency room drama will be shown on the show — Kim and boyfriend Kanye West have vowed to keep their tot out of the spotlight, after all — headlines are breaking over Kim K.'s post-baby bod!

Nori's mom is proudly showing off her renewed svelte figure just four-months after giving birth in a photo shoot for the Kardashian Kollection's new line at Lipsy London. The brand even Instagrammed a first look of the designs on Sunday, writing, "First Look @KardashianKollection for @LipsyLondon Check it out on @FabMagPics & in Sunday Times Style #KardashianForLipsy."

While Kim certainly looks great, it seems many are divided about her return to the spotlight. What do you think?
