Is Rob Kardashian cheating ... on his diet?! It looks like it!

Rob and his woman Blac Chyna took a break from dieting to grab some burgers at In-N-Out on Thursday afternoon.

This is the second time in a week the couple has hit the iconic fast food eatery in the last week. A week ago they hit up In-N-Out to celebrate Rob's birthday -- and just a week later the couple was back at the same spot, this time ordering six burgers. That's right -- SIX. We hope they aren't all for Rob -- but we wouldn't be surprised!

There's been a lot of talk of Rob's weight loss and how Chyna's helped him shed the pounds but it looks like the two couldn't help themselves -- and we can't blame them, the burger joint is delish!

While we know Rob loves In-N-Out -- we aren't sure how much mama Kris Jenner will love seeing him back noshing on his favorite guilty pleasure (let alone six burgers) after the former recluse has made so much headway in the past two months.

Of course Chyna took the opportunity to Snapchat their adventure to the Tarzana fast food joint, because it appears as though not one minute of their relationship can't go unnoticed.


Yesterday Us Weekly reported that Kris was thankful to Chyna for helping her troubled son rejoin the world. A source told the mag, “The whole family sees that it’s her who brought Rob back Kris is so grateful to Blac Chyna for rehabilitating her son."

She's rehabilitating him right back to the burger joint!

Kris also did an interview on Australian radio show "Kyle and Jackie O" this week and she talked about her son and his new girlfriend, whom she called "a really nice girl." The 60-year-old said, "He's doing really, really well. He feels much better about himself. He's trying to just get healthy and get in shape, and he's been working on a few projects and we celebrated his birthday last night at Nobu Malibu with the family. It was really, really great."

While Kris is saying she is grateful to Chyna, there's another celeb who is praising the new couple -- Chyna's bestie, Amber Rose. “I love them together … They are supersilly together," Amber told Us Weekly. “They literally crack up and laugh all day long, like it’s not just a front for social media. They’re really supersilly, and they love each other, and they have a blast together. I’m really happy for her. She deserves it.”

The twosome seem to be all about each other since they began dating two months ago. They have been non stop about showing their relationship via social media (even though they said they were going to take a break to be more private, we think that "break" lasted about five hours).

Yesterday, Chyna shared a smiling snap of the over-the-moon duo -- and they look pretty happy if you ask us. Rob even spent some quality time with Chyna's son King Cairo yesterday, taking the 3-year-old on a shopping spree to Toys R Us.
