The 20-year-old television personality has been dating the 26-year-old rapper since April 2017, and they had their first child Stormi together in February.
The couple recently appeared at the Met Gala together in matching black.
She wrote in the caption: ‘Stormi’s Parents’.
The caption came after rumors have swirled that Kylie’s bodyguard or her ex Tyga could be Stormi’s father.
While the theme of the gala was Heavenly Bodies And The Catholic Imagination, Kylie and her beau did not take the dress code too literally.
While some of her fellow guests went all-out high church, Kylie instead wore a simple peekaboo black Alexander Wang gown, complete with a train.
She kept the accessories to a minimum, with a pair of retro spectacles and a couple of bangles. Later the starlet was spotted leaving the affair separate from her love.
The day after the Gala, the parents of the three-month-old girl seemed to celebrate as they indulged in some sneaker shopping at a downtown store.
The couple were seen locking lips and embracing one another while making their way along the curbside.
Kylie may have also been using the Instagram post to throw some shade at her ex Tyga.In April, she granted her ex-boyfriend wish for Stormi Webster to undergo paternity testing, according to reports from The Sun.
An insider alleged that the timing of Kylie and Tyga’s breakup which reportedly happened in April 2017 was the same as the start of her relationship with Travis.
