Kourtney Kardashian and Khloe Kardashian enjoyed a sisters' night out on Monday after the 2016 Grammy Awards, hitting up Justin Bieber's after-party at The Nice Guy in West Hollywood hosted by Scooter Braun.

The ladies looked gorgeous in two different, black jumpsuits. Kourtney donned a see-through lace number that showed off her legs, while KoKo opted for a cut-out solid ensemble that revealed ample cleavage.

Of course, the sisters' arrival at the party sparked old rumors about Kourtney's speculated romance with the 21-year-old singer.

There were rumors of the two getting cozy during a few outings last October, but whenever asked about their "romance," they either laughed them off or joked about them—never actually denying or not denying them.

However, it seems the steam has definitely cooled off between the two. A source tells us they had "no interaction" at all during Kourtney's first Grammys after-party stop. The eldest of the Kardashian sisters stopped by 1OAK and actually ran into James Harden and French Montana (as well as the Biebs) at the nightclub.

"Kourtney and James weren't seen talking. James was at his table and Kourtney was hanging with French and Bieber," a separate source explained. "It was a crazy night, the place was packed."

"Khloe and Kourtney were there with Cory [Gamble] having dinner," the insider dished. "They had two other girlfriends that were there. They had no interaction with Justin Bieber."

The source also noted, "Justin was a good boy. He was with Scooter and his pastor Judah [Smith] for most of the evening."

Not to mention, Bieber is currently connected to Hailey Baldwin.

Though the two claim they aren't exclusively dating, Bieber told GQ she's someone he "really loves" and enjoys spending a lot of time with.

E! News also caught up with Baldwin last week during New York Fashion Week, and she further explained, "We are not an exclusive couple. He's about to go on tour. Relationships at this age are already complicated, but I don't really like to talk about it because it's between me and him."
