Sister, sister! Kylie and Kendall Jenner‘s recently revealed August tiff seems to be well in the past, as the stylish duo spent Monday night at a party together.

Both siblings shared videos on social media from their night out at what appeared to be a friend’s birthday party.

In one clip, 19-year-old Kendall and 18-year-old Kylie performed a little choreographed handshake while music boomed in the background.

Kylie wore a long-sleeved white top for the party, while her model older sister donned an off-the-shoulder sweater and a Yeezus baseball cap.

“Unrehearsed. no no,” Kendall wrote.

In another clip, the Jenners posed with their heads down and lip synced along to a song while the camera bobbed about.

Active snapchatter Kylie also used her camera to document the evening, sharing a range of videos with Kendall.

In Sunday’s episode of Keeping Up with the Kardashians, Kylie and Kendall got into a tiff after the former invited her boyfriend Tyga along on their family’s girls-only trip to St. Barts in August.

“It’s kind of annoying because I was really looking forward to being with Kylie on this trip, and it’s not even about Tyga, it’s more that just I know she’ll kind of be taken away from me,” Kendall explained to her sister Khloé Kardashian during the episode.

Both girls spent the holidays apart as Kylie visited Mammoth Lakes, California, with Tyga, while Kendall cavorted with Harry Styles in both Anguilla and St. Barts.
