Pregnant Kylie Jenner wore a pink dress to Stormi at Chicago West’s birthday party

Dressed in a Barbie-themed pink outfit, Kylie Jenner attended a joint birthday party for daughter Stormi Webster and niece Chicago West. According to E! News, her latest social media posting set off rumors that she had already given birth to her second child. The beauty mogul showed off her growing baby bump with a video selfie she posted on her Instagram story.

Totally in step with the party doll and Barbie theme, Kylie paired a bubblegum pink turtleneck catsuit with a matching pink oversized coat.

Keeping her jet-black hair down and parted down the middle, she completed the eye-catching ensemble with earrings, pink eye shadow, long lashes and mauve-hued lips.

Kylie shares Stormi, who will officially turn 4 on February 1, with rapper Travis Scott.

The fun-filled day was also joined by Kourtney, Khloe Kardashian, Kris Jenner and Chicago parents Kim Kardashian and ex Kanye West.
