Kim then excitedly replies: "We're having a baby!"
The reality star left no stone unturned as she transformed her Los Angeles residence into a dreamy cherry blossom forest and shared a series of snapchats showing off the lovely decoration.
Can't blame fans and followers for assuming that Kim was just teasing the guests and her social media following with a passive gender reveal event as well, considering that one particular colour was constant throughout the celebration - from party favours to the decorations.
I dunno about you but I'd be pretty mad at my sister trying to steal my limelight like that, especially if my sister was Kim Kardashian, but maybe that's just me? No sir. The internet was convinced that Kim's pink themed bonanza was hinting she's expecting a baby girl, just like Ky's recent rose coloured manicure and ring snap on Instagram. She's very excited about the baby, though.
The only celebrity pal to make the guest list was model and fellow Twitter star Chrissy Teigen, while Kim's close friend and hairstylist Jen Atkin, and eyebrow artist Anastasia Soare, also made the cut. Khloe Kardashian's beau Tristan Thompson also surprised his ladylove with a birthday party at a popular hotspot in Hollywood.
"She spoke to the surrogate, who said she'd been feeling the same".
