With the arrival of Dream Renee Kardashian, who was born 9.18am PT in a c section weighing 7 lbs and 5 oz, the newborn's surrounding family rushed to the Cedars-Sinai Medical Center in Beverly Hills to join Rob and Blac.

However, it appeared the Olympian was taking her own time.

The I Am Cait star - who is a supporter of Donald Trump - showed off her long and slender legs in faded denim jeans, cut off before the ankle, which she paired with a red sweater and black sandal flip-flops.

Wearing her camel-brown tresses down by the sides of her face, Caitlyn matched it with brown sunglasses and donned a black purse over her shoulder.
