Later, the reality TV star admitted she didn't capture many videos of the magical moment, because she didn't see initially thought it was just a "random date night" Kai had set up.

She said: "Okay, the biggest thing just happened! We don't have many videos of the proposal but I did not expect or see this coming. I honestly thought it was just a random date night that Kai had put together but yeah, I am so shocked and happy!"

To finish the evening, the happy couple enjoyed a romantic meal out before heading back to a hotel room which had been kitted out with balloons, petals and a collection of photos from their time together.
