Kylie Jenner and Kendall Jenner didn't let father Bruce Jenner's car accident affect their weekend plans.

The teenage reality stars were spotted with brother-in-law Kanye West, Justin Bieber, Jennifer Lopez, Demi Lovato, Chris Brown, Alfredo Flores and J. Cole at a Big Sean show Saturday, hours after Bruce Jenner was involved in a fatal car accident that left one woman dead.

Lovato shared a selfie of the group on Instagram, and included the caption, "#wheresdemi #iseeyou." Kylie and Kendall Jenner later attended the E! Grammy Awards after party with half-sister Khloe Kardashian, who hosted the bash Sunday.

Kylie and Kendall Jenner announced they will design a new fashion line for Topshop last week.

The sisters previously launched clothing label Kendall & Kylie at PacSun stores, and released a special Valentine's Day collection for the brand Sunday.
