The feud between Blac Chyna and the Kardashian family seems to be heating up. The 27-year-old model, who was recently rumored to have a romantic relationship with Rob Kardashian, reportedly compared Rob's skills in bed to her ex Tyga, claiming that the former was better than the latter.

According to HollywoodLife.com's source, Blac wanted people to know how great her and Rob's sex life was. "Blac Chyna is totally playing to Rob's ego, she's been telling him that he's better in bed than Tyga. He hasn't had this much attention from a woman in a long time, she's got him sprung," the insider said.

The source speculated that Blac did this to get back at her longtime enemy Kylie Jenner, whom she accused of stealing Tyga from her. "A lot of people are convinced she's just playing him and it's all just about getting back at Kylie, but it definitely is doing Rob good in the short-term," the insider continued.

Blac spread the dating rumor on January 25, the same day Tyga admitted he wanted to marry Kylie. She posted a sweet Instagram photo which featured herself embraced by Rob. Ever since the dating rumor broke, there has been a lot of reports about dramas that happened in the Kardashian dynasty, including the one saying that Kylie felt "super betrayed" and could not "understand why someone in her own family would stab her in the back like that."
