She won't let anyone see her sweat!

Kris Jenner hit the gym in L.A. this morning, and we have a feeling the momager was trying to work off some of her anxiety over ex-husband Bruce's tell-all Diane Sayer interview, which is set to air this Friday. The reality star might not be the biggest fan of her former spouse right now, but she's a huge fan of daughter Kim's husband Kanye West as evidenced by her Yeezus tour jacket.

Our videographer also asked the mother-of-six why other daughter Khloe has yet to visit her stepdad since the transitioning rumors surfaced, but the Kardashian matriarch must not have wanted to answer that, because she quickly got into her ride and sped off.

There are rumors Kris is thinking of suing Bruce if he reveals any family secrets during this upcoming sit-down about his gender reassignment, but we have a feeling he's too smart to spill the beans on America's most famous clan.

The 59-year-old must be mortified that her longtime marriage was a big lie!
