The beauty mogul celebrated daughter Stormi's seventh birthday on Feb. 1 and son Aire's third birthday on Feb. 2

Kylie Jenner is ringing in son Aire’s 3rd birthday with a minions-themed bash. Jenner, 27, offered a glimpse of the festivities via her Instagram Story on Sunday, February 2. In one snap, Jenner showed a pile of yellow presents with blue ribbons and matching balloons.

Now, Kylie has broken her photoshoot-heavy grid to drop the *cutest* video of Stormi and Aire in honour of their birthdays. The Webster kids, who were famously born just a day apart (Stormi on the 1st Feb and Aire on the 2nd), look so grown up in the video, which Kylie captioned: "my world. happy birthday to my babies."
