Whether she's concerned about her son or concerned about bad press is the question!

Kris Jenner and her boy toy Corey Gamble caught the first flight out of St. Barth this morning after news broke yesterday that her son Rob was hospitalized and diagnosed with diabetes, and it seems the momager is keen to get back to LA and get hands-on with the problem.

A source on the island tells X17:
    "Kris seemed frantic and stressed out. She was on her phone the whole time while they waited for their flight to take off. She never once took her sunglasses off, because she was super puffy and had obviously been crying."

The Kardashian matriarch and her man had been vacationing with Nancy C. Rogers and her husband Richard Rogers, the owner of Mary Kay cosmetics, who rented a luxury yacht for the trip.

First Lamar, and now Rob... Kris has had her share of medical crises to handle this year!
