Rob Kardashian is clean shaven and flirting with Blac Chyna in new Snapchats

We're seeing a lot more of Rob Kardashian since he started dating Blac Chyna.

Photos obtained by ET earlier this week showed the Keeping Up With the Kardashians star with a full beard as he arrived to the 27-year-old model's home. But when Rob started Snapchatting on Thursday night, the facial hair was gone.

The video was taped in the car and posted by Chyna. The giggly couple appear to be talking about Rob's diet when she asks, "So, listen, Rob, do you know what collard greens is? Yes or no?"

When he admits to not being familiar with the dish, his girlfriend replies, "Imma make you some collard greens tonight, I promise."

So far, the 28-year-old reality star's relationship with Tyga's ex-girlfriend appears to be pretty positive. "He's lost weight, actually," a source close to Rob told ET, "and is madly in love with Blac Chyna!"

Last week, Chyna's best friend, Amber Rose, said that the new romance was pushing Rob in a healthier direction.

"They're working out. Chyna's cooking healthy meals for him," Rose said on the Allegedly With Theo Von & Matthew Cole Weiss podcast. "Rob is the coolest guy you'll ever meet in your life. He's realistic, he's an amazing person, and it's sad that people don't get to see that. He's just down to earth and cool."
