Kim Kardashian turned 35 yesterday, and celebrated her birthday with a surprise pregnancy-themed party.  

The bash, thrown by husband Kanye West, involved a tiered wedding cake with a backdrop of pale roses plus a few more unusual elements (more about this later). Taking to Instagram, the KUWTK star wrote, 'My husband never ceases to amaze me!'

She also revealed that the evening included a private screening of Steve Jobs (Kim's review? 'It's sooooo good BTW'), and most bizarrely, guests wearing fake baby bumps on arrival, seemingly to make Kim feel more at home. It appeared to work, as she added, 'I had the best time ever, feeling so very comfortable eating churros with a bunch of pregnant women!' When it comes to Kim, nothing surprises us anymore.
