Kylie Jenner and Kourtney Kardashian recently hung out with their brother Rob Kardashian’s ex-girlfriend Adrienne Bailon — and they shared their sweet get-together on Instagram on Sunday, February 28.

“Cause we are sistersss,” Jenner, 18, captioned a photo of Kourtney, 36, and Bailon, 32, sitting on her lap.

The eldest Kardashian sister posted a similar shot with the caption, “Reunited best friends lol.”

Bailon and Rob dated for two years before they broke up in 2009. In a 2010 episode of Keeping Up With the Kardashians, Rob admitted that he was unfaithful to her.

The once-reclusive reality star is now dating Blac Chyna, despite the fact that the Kardashian-Jenner clan is struggling to deal with the situation, as previously reported by Us Weekly.

As for the lovebirds’ feelings on the new photos with Bailon? “Rob and Chyna are laughing over it,” a source tells Us. “They think she’s being ridiculous.”

Chyna, 27, shares a 3-year-old son with Kylie’s boyfriend, Tyga.
