Kim appeared relaxed and happy as she played with her two-year-old daughter, who looked adorable in a cream outfit and matching sandals.

The tot was having a great time and was pictured gazing at a candy display full of M&Ms and sour Skittles which were available for guests.

They were even snapped trying on fake bumps and rapper Tyga wrapped his arms around girlfriend Kylie.

Kim stunned in a beige and showed off her bump, while writing on her site: "Kanye never ceases to amaze me!!! He threw me the best surprise party and had everyone wear fake baby bumps to go with the pregnant theme."

"I loved all of the little details he thought of. It was so fun celebrating with my closest friends and family."

The reality TV queen had lunch and cake and added: "We got to watch the new Steve Jobs movie together. There were even churros! I had the best time ever!
