Rob Kardashian is adding more fuel to the circulating rumors that he is dating the Kardashian family's nemesis, makeup artist Blac Chyna, Us Weekly reported. The only son of the Kardashian clan posted an extreme close-up shot of Chyna's face and posted it to his Instagram page.

The photo is a tight shot of Chyna's face and shows off the 27-year-old's nose, lips and light brown eyes as she looks off into the sunlight. Kardashian, 28, simply added the round push pin emoji in the caption of the post.

Kardashian's post is his second since rumors of his relationship with Chyna broke, as previously reported by HNGN. He also posted a meme of Chyna on Monday that suggested Chyna is preparing to carry Kardashian's child.

Chyna was once friends with Kardashian's older sister Kim, and she even attended Kim's 2014 wedding to hip-hop artist Kanye West, People reported. Chyna and Kim's friendship went south in October 2014 after rumors that Kylie Jenner was dating Chyna's ex-fiancé, Tyga. The 25-year-old "Rack City" rapper and Jenner confirmed their relationship after her 18th birthday last year. Chyna shares 3-year-old son King Cairo Stevenson with Tyga.

Jenner and Tyga's relationship also caused a Twitter feud between Chyna's best friend, model Amber Rose and Jenner's older sister, Khloé Kardashian.

A source close to the Kardashian/Jenner family confirmed that Kardashian is dating Chyna, E! News reported, but family members are concerned that Chyna is using Kardashian to get back at Jenner.

Chyna posted a photo of what appeared to be Kardashian's arm around her in an embrace and also posted videos to her Snapchat of her working out with Kardashian, according to Us Weekly, but neither Kardashian nor Chyna have officially confirmed their relationship status on social media.
