On Tuesday, rapper French Montana – who is Khloé Kardashian's ex – took to Instagram to share a video of him and Rob joking around.
"Get them bags ready we coming," reads the text imposed on the video, which was originally posted to Montana's Snapchat.
"@robkardashian get ready!!" the rapper captioned the clip.
Rob, 28, and Montana, 30, are longtime friends. The hip hop artist has also remained friends with his ex, Rob's sister Khloé, 31.
Rob has been more active and less reclusive since news broke in late January that he is dating Blac Chyna, 28.
After the relationship created tension amongst his sisters because of Blac Chyna's complicated history with the famous family, he moved out of Khloé's house and was staying with Blac Chyna for some time before purchasing his own home.
Last week, PEOPLE confirmed Rob bought a $2.285 million, four-bedroom, 4,256 square-foot home with the help of mom Kris Jenner in the celeb-studded neighborhood of Calabasas, California, also home to several of his family members.
Sources say Rob and Blac Chyna will continue living together once Rob moves into his new home.
