Kim Kardashian: I Don't Always Wear My Wedding Ring!

Kris Humphries put a ring on it, but Kim Kardashian isn't wearing that sparkler 24/7!

The 30-year-old newlywed has some serious bling: her 20.5-carat platinum engagement ring is worth an estimated $1 million, and her platinum and diamond Lorraine Schwartz wedding band is worth around $200,000.

"[But] I don't wear [any jewelry] to work out," she told Women's Wear Daily in an interview published Tuesday. "I was leaving the gym yesterday and I didn't have my [wedding] ring on, and there [were] all these photographers taking pictures, and I said to my sister, 'Just watch, Kourtney. You will see a story [bearing the headline] 'Kim Without Her Ring. Trouble in Paradise.'"

But rings aren't the only jewelry the reality star has banned from the gym. She's boycotted jewelry altogether any time that she's breaking a sweat. "I see women coming to the gym with earrings on, " she said. "I can't do it."
