Rob Kardashian has joined Snapchat.
The reclusive reality star made his app debut, under a rather rude handle, on Monday with a selfie video appearing to be in good spirits laughing and smiling.
Kardashian’s girlfriend Blac Chyna took to her own account to encourage fans to follow his account, but had a a few choice words.
In a NSFW video posted the same evening, Tyga‘s former fiancée delivered a warning to female followers by saying, “Lemme tell you all something, don’t be snapping my boo that p—y. I ain’t f–king playin.”
The model later took to Instagram to share a sexy new photo of her wearing a black fishnet dress – and not much else.
In the image, Blac Chyna crouched in front of a mirror, with her bare bum completely visible.
“Eat your heart out,” she wrote.
“Rob has been lonely for so long, so of course it’s great for him to spend time with someone other than his sisters,” a source told PEOPLE.
