Khloe Kardashian goes ringless on 8/23/13 (Splash News)
Kardashian was photographed leaving Equinox gym in Woodland Hills, California, and her 12.5-carat sparkler was noticeably absent. The 29-year-old has been photographed leaving the gym with her ring firmly on in times past.
"She didn't smile at all and seemed miserable," a fellow gym-goer told People. "She seemed like she had a lot on her mind."
Odom, 33, and Kardashian have not specifically addressed the latest round of cheating allegations, although Khloé tweeted out a cryptic Instagram post this week.
"Never judge someone without knowing the whole story. You may think you understand but you don't," Kardashian shared on Wednesday. She added: “Stop trying to figure me out and get to know yourself first."
However, Lamar has stayed quiet on Twitter. When infidelity rumors first surfaced in early July, Odom denied they were true. He also tweeted:
Adding fuel to the splitsville fire is the fact Lamar has reportedly been staying at a hotel close to his Tarzana home he shares with Khloé. He was also noticeably absent at Kylie Jenner's huge sweet 16 bash last weekend.
Mama bear Kris Jenner denied divorce reports recently to E! News, although she didn't specifically address the cheating rumors.
"Khloé and Lamar are absolutely not getting divorced," she said. "There's been no talk of divorce."
Kardashian and Odom's fourth wedding anniversary is next month.
