We haven't seen or heard from him in over a year, and now he's out and about and posting up a storm on social media! What gives?!

Rob Kardashian and his new girlfriend Blac Chyna went for a drive around the stripper's Tarzana neighborhood today in his black Bentley, and it certainly didn't seem like they minded having their photograph taken!

The reclusive reality star was wearing a Dodgers hat pulled down low, so it's hard to tell, but we think he looks like he's already lost some weight. That could be because Blac hired a trainer to get her new man into shape! That trainer also dished to Us Weekly that the single mom is already calling Kimmy K's brother her "boyfriend," so it looks like it's official! Meanwhile, it looks like Blac could drop a few pounds ... as the cheek-pierced lady headed in to the nail salon, we got a good look at her backside, and girlfriend is packing some serious junk in her trunk!


In related news ... Blac's ex and baby daddy, Tyga, finally broke his silence on Rob and Blac's new romance, and it sounds like he's opting to take the high road! "Everybody deserves to be happy," he responded when asked about it while leaving a friend's house on Wednesday. Considering he shares son King Cairo with Blac and he's now dating Rob's sister Kylie, this has got to be at least a little awkward!

The sock designer's sister Khloe kicked him out of her Calabasas mansion when she learned of their relationship, so he's been shacking up at his new lady love's pad for the past week. His ride was even parked in her driveway this afternoon, as you can see in the below pic.

We can't wait to see how this whole situation plays out!
