Josh Brolin’s Struggling Brother In Health Crisis

Josh Brolin is showing off his super-shape as Cable in "Deadpool 2"  —  but he hasn't shared any health tips with his younger brother Jess, whose pound-packing ways may cost him his legs!

The National ENQUIRER’s spies recently spotted tragic Jess, who is also the stepson of detached, dog-cloning diva Barbra Streisand, devouring a sandwich at a community-assistance program in Ojai, Calif., his flabby ankles dripping with festering sores.

Shockingly, moments later the son of Barbra’s hubby, James Brolin, huffed his way to Lisa’s Cantina — a sports bar known for its cheap beer and calorie-heavy Mexican fare. “Those are venous stasis sores on his legs,” said Dr. Charlie Seltzer, a physician who has not treated the 400-pound, formerly homeless dumpster diver.

“Any wound he gets will have trouble healing, and could ultimately lead to an amputation," said the doctor “It’s a ticking time bomb. At the very least, he needs an intervention from his family. I wouldn’t be surprised if he had a heart attack tomorrow.”

The ENQUIRER first exposed Jess’ dismal existence in 2014, publishing photos of him fishing food from a trash can! A year later, our spies caught him grubbing a free Thanksgiving meal from volunteers in a California park — while Barbra, who is worth about $550 million, lives it up in a Malibu mansion!

At the time, Jess implied he hadn’t heard from his family in some time. “Get them to say it’s okay to talk and I’ll talk,” he said. “They have my phone, they can get hold of me.”

Josh, meanwhile, is in the best shape of his life after pumping up in the gym to play the heavily armed tough guy Cable opposite Ryan Reynolds in the "Deadpool' sequel. “It’s amazing how one brother turned out one way,” an insider spilled, “and the other is a megastar!”
