Kylie Jenner has thrown a surprise birthday party for Tyga.

The 19-year-old model took to Snapchat on Thursday (17.11.16) to share videos and photos of the small surprise party for the rapper - who turns 27 on Saturday (19.11.16) - with the help of his son King Cairo.

One video - also posted to Kylie's Instagram account - sees King Cairo, four, stood on the kitchen table surrounded by balloons, whilst the lip kit mogul holds onto his waist for safety. As Tyga walks in the door, they start to sing him 'Happy Birthday', with the 'Rack City' hitmaker completely stunned.

Another features Kylie handing Tyga a painted ornament of the word ''dad'', made by the toddler.

Tyga says to his son in the video: ''Aw thank you man! Gimme a high five, gimme a high five!''

To which King Cairo instead goes in for a cuddle, before being picked up by his dad.

Tyga then asks: ''Did you paint this yourself?''

And King Cairo says: ''Yeah!''

Tyga then tells him: ''I like it.''

And Kylie spared no expense on the wide spread of food that was laid out for the 'Ayo' rapper, making sure to include some his favourite foods such as fried chicken, and two separate cakes.

The rest of the night was spent playing around with Tyga's son - whom he shares from his previous relationship to Blac Chyna, who is now engaged to Kylie's half-brother Rob Kardashian - as one video captures the boy sat in a fabric tunnel toy, giggling and screaming as his dad comes to catch him.

The news of the small family party comes after Kylie was noticeably absent from Tyga's celebrations last year as the pair had gone on a break a few days before he turned 26.
