Stepping out for some sisterly fun, Kendall and Kylie Jenner arrived at 102.7 KIIS FM's Wango Tango at The Home Depot Center in Carson, California on Saturday (May 11).

The eldest sister rocked a gray cutoff T-shirt, black pants, and pointy black pumps, while her younger sibling wore a sleeveless black midriff-baring top, high-waisted black pants, and red heels.

Hosted by Ryan Seacrest with a special guest host appearance by Britney Spears, the annual day-long concert also features performances by will.i.am, Bruno Mars, Maroon 5, Demi Lovato, Avril Lavigne, and Fall Out Boy.

Though the sun was shining on the gorgeous day, it seems guests and performers may have been feeling the heat at the show, as Kendall tweeted on Saturday, "If it's this hot already, I am not excited for what's to come this summer."
