Khloe is one strong lady! Khloe Kardashian kept a stiff upper lip as she headed to the studio in Los Angeles, amid reports that she can't find soon-to-be ex hubby Lamar Odom to finalize their divorce. Umm ... yikes! Can't Khloe get a break!

Despite filing divorce papers over 10 months ago, Khloe and Lamar are still not officially dunzo, in part because the tallest Kardashian can't get in touch with the former NBA star, reports Us Weekly. "Khloe can't even get in touch with him right now," an insider told the mag. Another source said, "He refuses to sign the divorce papers."

Despite the split snafu -- Khloe is doing what she does best -- rolling along! For her afternoon at the studio, the star wore a tan wrap blouse, white jeans and see-through heels. How very Kimmy K of her! Looks like things got heated in the studio -- we couldn't help but notice her pretty intense pit stains!

Meanwhile, pregnant sister Kourtney was looking too cute as she headed into the studio to film segments for Keeping Up With the Kardashians. The mother of two showed off her stems on Wednesday when she wore a bodycon minidress, fringe denim jacket and ankle boots.
