“Yes!” Harden shouts. “Greatest in the f–king world…The biggest in the world!” 

After the event, Kylie traded in her casual ensemble of a white t-shirt and acid wash jeans for a denim mini-skirt—similar in style to one that older sister Kendall Jenner recently wore—a red and white cropped motorcycle jacket and a pair of strappy, black heels.  

Travis and his girlfriend matched an outfit, wearing a red and white motorcycle jacket. The back of the jacket had lettering that said, “riders”. The look was complete with white pants and sneakers. 

Travis posted a photo of Kylie and him walking together in an event venue on his Instagram Story with the caption “riders for life”.
