The 26-year-old rapper, who has a child with his former partner Blac Chyna, decided to celebrate his fourth birthday with a race-car themed party on Sunday (16.10.16), which Blac had put on merely one day earlier.
The 'Rack City' rapper child was surrounded by sports car decorations, including a racing car made entirely out of balloons that rested on top of the swimming pool, a racetrack, a Ferris wheel, a trampoline, an inflatable slide, and horses at his party, which took place at Kylie's Los Angeles home.
The 19-year-old beauty mogul's family, including Kendall Jenner, Kourtney Kardashian, Scott Disick and their three children Penelope, four, Mason, six, and 22-month-old son Reign, joined the couple and King to celebrate the special day.
Kim Kardashian West also attended the event with her three-year-old daughter North, as well as 60-year-old momager Kris and Caitlyn Jenner.
And the Kylie Cosmetics founder, who broadcasted the event over social media, has credited her boyfriend as the "World's best dad".
Alongside a picture of her beau wearing an all red Ferrari tracksuit at the celebration, which was shared on Kylie's Snapchat, the 'Keeping Up With the Kardashians' star wrote: "He did such a good job. World's best dad (sic)."
Kylie also took the time out to take a selfie of her, which saw her clad in a black two-piece with the Ferrari motif on, to her Instagram account, and another post saw her adorn a white body con suit whilst Tyga cosied up behind her.
Tyga also took to social media to share moments from his son's birthday.
Alongside a picture of him with his son sporting matching ensembles, he wrote: "The swaggiest Littlest man doing it!!!happy 4th bday to the young legend!!! (sic)."
Meanwhile, Blac celebrated her child's birthday, which only Kris attended, on Saturday (15.10.16), with a Lego Ferrari theme.
