Being an agoraphobe isn’t hurting Rob Kardashian’s luck with the ladies. He’s being linked to none other than Blac Chyna.

The bootylicious personality, 27, posted an Instagram photo on Monday that shows her face, her cleavage (natch), and a man’s tattooed arm around her. “The beginning,” she wrote along with a lucky shamrock.

The Internet quickly deduced that the fellow with the thorny heart tattoo is none other than Kim Kardashian’s little brother. The one who may be diabetic. The one who rarely leaves home — unless it’s to go see Blac Chyna apparently.

E! confirmed that Rob and Chyna are dating, but a source says there is “concern” regarding the relationship because some feel she is “preying” on Rob “during a weak time.”

Also making this new romance a little ew-ville is the fact that that Rob’s little sister Kylie Jenner, 18, is dating Chyna’s baby daddy, Tyga, 26. Could Chyna be toying with Rob to get back at Kylie? The two have feuded in the past, so Christmas celebrations could get … complicated. For his part, Rob has dated Adrienne Bailon and Rita Ora. Neither relationship ended well.

Blac is an old friend of Kim’s, though it’s unclear how often they catch up now that Kim is knee-deep in diapers. Make that: Kim’s nannies are in knee-deep in diapers. The urban model is busy herself rearing her 3-year-old son, King Cairo Stevenson.

Now that Rob, 28, and Blac are together, we can’t wait to see what that means for Arthur George. Will his sock line get sexier? Will there be cutouts to show toe cleavage? Padded heels? Pierced hemlines? Oh, we can’t wait to find out.
