Rob Kardashian sparked rumors of dating Chris Brown's ex-girlfriend Karrueche Tran after he shared her photo on his social media page. The former "Keeping Up With The Kardashians" star already deleted the photo and has since responded to the rumors.

Rob slammed reports he is dating Tran on his Instagram page. According to US Weekly, the 28-year-old said, "Yall dumb af. I been Friends with Karoooooch since high school. F**k outta here with your negative s**t."

His response came after he shared a photo of Karrueche on his Instagram account and captioned it, "I like when she send me pictures," along with a couple of heart emojis. Rob has since deleted the photo, but not before it was grabbed by multiple news sites. Daily Mail shared the Instagram snap, which shows Karrueche's face looking thoughtful as she stares at the camera.

According to Daily Mail, Rob shared Tran's photo on Tuesday and it instantly racked up thousands of likes. It also created a stir among followers of the Chris Brown- Karrueche Tran relationship drama.

It is believed to be a bold move for Rob to post the photo, considering how Chris had reacted negatively to the men being linked with Tran following their split. Daily Mail claimed Breezy had previously threatened men who were linked or made remarks about the 27-year-old model on social media. The couple reportedly dated on-and-off between 2011 and 2015, but Tran broke up with the rapper after she learned of his child with another woman.

Tran had since spoken up about Brown's jealousy with TMZ, saying that she doesn't understand his behavior, especially since she is already single.

"I thought we have all matured and moved on especially since Chris has been seen with multiple women since the breakup. I don't want anything to do with any type of violence or negativity," she said.

Just recently, Brown reacted to Drake's track with Future, "Live from the Gutter" on his Instagram page. Some lyrics in the song were reportedly meant to diss Chris and Karrueche. The lines "This for my n****s on that bulls**t and that nonsense / This for my dogs that go Karrueche with the chopsticks" clearly speaks of Brown's ex.

As for Rob, the 28-year-old has not been linked to any woman recently. Hello Magazine claimed he once dated Adrienne Bailon and Calvin Harris' ex-girlfriend Rita Ora until they split in 2012.
