Well, this might make for some awkward family dinner conversations.

Rumors are starting to abound that Rob Kardashian is dating Blac Chyna … as in Tyga's ex … as in Kylie Jenner's off-and-on boyfriend.

On Jan. 25, Chyna posted a photo to Instagram showing a heavily-tattooed arm wrapped around her, showing a sweet embrace. While she doesn't indicate who that arm belongs too, based on the ink, it appears to be the reclusive Kardashian family member.

"The beginning," she captioned the black-and-white pic, sharing it with her 4.6 million followers.

Multiple celebrity media outlets have studied the tattoos of the mysterious arm in Chyna's pic and matched it with tattoos from Rob's arm from when he was in the public spotlight more.

TMZ says that Rob and Chyna "have been together almost non-stop for several days" and that the hook up is fairly new.

Chyna has a long and sometimes convoluted history with the Kardashian family, although she and Rob never knew each other until recently. Several years ago Chyna and Kim Kardashian West were incredibly close, often being seen out together and littering each other's social media accounts. Chyna even lived next to Kris Jenner's house at one point.

Kim and Chyna's friendship, though, frayed after Kylie, Kim and Rob's half-sister, began dating Tyga, the father of Chyna's 3-year-old son, King Cairo Stevenson. As time went on, Chyna befriended Amber Rose, Kanye West's ex, before he married Kim.

Amber, while BFF with Chyna, blasted Kylie on a radio show early last year.

"She's a baby, she needs to go to bed at 7 o'clock and relax. That's ridiculous," she told 105.1's The Breakfast Club. "[Tyga] should be ashamed of himself. For sure. He has a beautiful woman and a baby, and left that for a 16-year-old who just turned 17."

Khloe Kardashian came to her sister's defense on social media, saying, "Please don't worry about my sister who has a career & her s--t together at ONLY 17 people who live in glass houses shouldn't throw stones. Please stop talking about us in interviews mama. None of us talk about you."
