It's anyone's guess what's next for Khloe Kardashian and Lamar Odom. For the first day of filming season 9 of Keeping Up with the Kardashians in L.A. on Monday, Sept. 9, Khloe, 29, looked sleek and stylish as she chatting on the phone in a checked, cinched jumpsuit, lace-up platform boots, blue Hermes bag and sunglasses. Her most glaring accessory? Her wedding ring from Odom, 33.

Although Kardashian and the NBA free agent's fourth wedding anniversary is this month, things are far from rosy for the pair, whose estrangement -- in the wake of Odom's drug abuse and reported affairs -- have been dominating headlines for weeks.

"She doesn't want to talk about it, which is characteristic," a friend of Khloe's recently told Us Weekly. Although the star has been tweeting and Instagram vague messages of empowerment -- or just off-topic, silly stuff --- Kim and Kourtney's sister is "honeslty stronger than everyone thinks," another friend insists.

Odom, meanwhile, also resurfaced several hours earlier without his famous wife. Following a blink-and-you-missed it rehab visit last week, the former L.A. Laker was photographed visiting a sushi restaurant and convenience store near his L.A. loft past midnight on Monday.
