Inside Rob Kardashian and Blac Chyna's ''Sexy'' Relationship: Find Out What Makes the New Couple Work

Model is giving her man the attention he needs

It's fair to say that a lot of people are confused by Rob Kardashian's decision to date Blac Chyna, considering she's his little sister's boyfriend's ex-fiancé (are you still with us?).

But despite the drama surrounding Kylie Jenner and Tyga, Rob has found a romantic connection with Chyna, and, quite simply, she makes him feel good about himself at a time in his life when confidence hasn't exactly been an easy feat.

A source tells E! News exclusively that Rob has been "taking better care of himself since his health scare," and Chyna is helping him continue along that path.

"She makes him feel really good and sexy," the source explains. "She gives him a lot of sexual attention."

As for how the couple first sparked the fire to their new romance, the source says, "Blac Chyna was friendly with Rob when she was good friends with the Kardashians. Rob always thought she was pretty hot."

Still, the amount of drama that's already stirred up between Chyna and the rest of the Kardashian-Jenner clan—who think she might be "preying" on Rob during a "time of weakness"—seemingly wouldn't bode well for the start to any relationship, let alone one as highly publicized as this. However, the insider says the model isn't letting it affect what she has going on with Rob.

"Black Chyna has not talked bad about the Kardashians but knows that her being with Rob will stir things up," the source says. "She really doesn't care because, as long as Rob and her are good, that's all she is concerned about."

The insider adds, "Everyone has to get over the fact that they dating. She is not planning on leaving Rob."

In fact, Rob is currently staying in Chyna's home, though our source notes "it's only temporary."

Meanwhile, Tyga finally spoke out about his ex and Rob for the first time on Thursday, shrugging off the news of their romance with a surprising remark.

"Everybody deserves to be happy," he told the paparazzi.  

As for his Kylie's feelings about the whole thing? She's simply not responding to Chyna. "Kylie doesn't want to give her the attention she so obviously wants," a source told us earlier this week. "Ky is ignoring her antics."
