Tight Leash! Caitlyn Jenner's Lover Bans Her From Attending Son Brody's Wedding

Don't come between Caitlyn Jenner and her woman.

RadarOnline.com can exclusively reveal Jenner will not be attending son Brody's destination wedding because her "number one priority" is her much young girlfriend, Sophia Hutchins, who has banned the 68-year-old beauty from attending the nuptials!

Meanwhile, Jenner refuses to let anyone cramp her style or interfere with her romance to the 21-year-old.

"Cait can go to Brody's wedding if she really wanted to. But she can't and won't because of her boss Sophia," a source connected to the Olympian revealed. "The truth is, Sophia's Cait's number one priority and they're inseparable.

"Brody's wedding date and all the traveling screws up things that Cait already has planned with Sophia," the source explained. "Sophia wasn't up for all the wedding extravaganza and because she wasn't, neither was Cait."

The source claims Jenner balls out on Hutchins, taking her on lavish shopping sprees and on cross county excursions. "Caitlyn spoils her rotten. Everything she wants: clothes, vacations, jewelry, all of Cait's attention, she gets."

Things are really going strong for Jenner and Hutchins. They were photographed hanging out in Malibu over Memorial Day weekend and are believed to be shacking up at Jenner's Malibu mansion.

As RadarOnline.com readers know, Hutchins wants the world to know she's cozy and comfortable living in her girlfriend's digs.

She posted a photograph on May 19 laying in what appears to be Jenner's bed. The headboard is a telling sign as the star herself has posted pictures to her social media accounts with that exact headboard in the shot.
