*After Rob Kardashian showed his Instagram followers a selfie sent to him by Chris Brown’s ex Karrueche Tran and reportedly shared a screenshot of their text messages, Tran has come out to explain that folks are all up in arms over nothing.
Karrueche Tran and Rob Kardashian are old friends … and the suggestive photo he posted was just her showing off her swollen face post-dental surgery.
Karrueche went under the drill Tuesday to have her wisdom teeth pulled.
We’re told Rob checked in on his pal and noticed she was talking funny … after they hung up, she sent him the post-dentist pic.
Our source says Karrueche isn’t mad Rob posted the photo and suggestive caption … they’ve been friends since high school and regularly talk.
