It was a family affair for the Kardashian-Jenners at The Weeknd‘s concert in Inglewood, California, on Wednesday night – but all eyes were definitely on Khloé Kardashian.

Wearing a curve-hugging and thigh-revealing ribbed black dress, the 31-year-old Strong Looks Better Naked author looked toned and trim for The Forum-held concert.

Joined by sisters Kourtney Kardashian and Kylie Jenner in an Instagram photo, the reality star looked slyly at the camera while she teed up at a virtual golf simulator. Kourtney’s hand was conveniently placed just above her sister’s impressive derriére.

The star arrived for the evening – The Weeknd’s second night at the venue – with mom Kris Jenner and Kendall Jenner in tow. All the women were dressed head-to-toe in black, with Kendall in over-the-knee leather boots.

Kris also appeared to get into the backstage hijinks, as seen on The Forum’s official Instagram account.

The matriarch grabbed a vacuum cleaner in the video and immediately got to work.

“Just vacuuming The Forum,” she said in the clip. “No problem. It was a little dusty in here when I got here.”

“Everybody’s workin’ for The Weeknd,” The Forum captioned.

The concert marked the first group outing for the family since sister Kim Kardashian West gave birth to her second child, son Saint West.

Kim, husband Kanye West, daughter North and Saint are still staying with Kris in her Calabasas home, PEOPLE has learned, and have already left the hospital to take up at their temporary digs.
