Rob Kardashian Talks Wedding, TV Specials and Cheating ... On His Diet

Rob Kardashian is now FULLY out of his shell ... he just talked to us about everything under the sun -- his wedding, his weight loss, and his biggest vice with Blac Chyna.

BlacRob just touched down at LAX -- returning from weekend appearances in NYC and Boston -- and he was a regular chatty Cathy. He addressed the story TMZ broke about producers making big money offers for them to televise their wedding.

Sounds like they're not impressed with any of the deals. Yet.

Rob also says he's dropped 40-50 lbs. so far, but he's not even counting anymore because he's too busy being happy. Just watch -- honestly, it's been years, if ever, since we've seen Rob this talkative.

He even broke some news to us about his driver license -- and let's just say Uber's gonna love him!
