Kris Jenner may not love Blac Chyna but it seems like she loves what the former stripper is doing for her son Rob Kardashian.

Two months after Rob and Blac began dating the former shut-in has been out and about all over the world. In the years prior, Rob locked himself away in Khloe's house and rarely went out -- missing Kim's wedding, skipping family trips and keeping to himself. But since he fell for Tyga's baby mama -- the reality star has been traveling the world and showing his face around town.

A source tells Us Weekly, “The whole family sees that it’s her who brought Rob back.." The source also adds that even Rob's overprotective mom is thankful. “Kris is so grateful to Blac Chyna for rehabilitating her son," the source added.

We will see how "grateful" Kris is when Blac gets knocked up -- but at least for now we're sure she's happy her baby boy is leaving the house for something other than his late-night In 'n' Out runs!

But it looks like Kris got her mind off of her son and his new lady love when she and her daughters Kourtney and Khloe jetted up to the Napa Valley for a little bit of wine tasting. The trio seemed to have a blast and definitely got day wasted at the tasting. Looks like the trip was a short one -- the gals were back in Los Angeles on Tuesday afternoon. The reality stars disembarked from their private jet after their fun-filled afternoon.
