Khloe Kardashian, Lamar Odom Marriage: Khloe Talks 'Sex Den' On 'Jay Leno' (VIDEO)

Khloe Kardashian Odom stopped by "The Tonight Show With Jay Leno" Tuesday to talk about how she cheered her husband up during the 149-day NBA lockout.

"Lamar had a really tough summer -- he experienced a loss in his family... I felt like everything was so down in our house," Kardashian Odom told host Jay Leno. "My brother moved out, that was really hard on Lamar."

Her solution to Odom's blues? A sex room. "I wanted to turn Rob's room into a sex den, a fantasy room," she said. "I wanted to make it fun and a playful environment."

Kardashian Odom said she bought a sex swing for the room, which she installed with a friend. But it didn't turn out quite as she had imagined. "My girlfriend Malika and I -- we tested it. We both got in it with our clothes on, and it worked perfectly," said Kardashian Odom, laughing. "It's Lamar's fault. The swing broke!"

The couple married in September 2009 after a brief one-month courtship. They recently moved to Dallas from Los Angeles after Odom, a pro-basketball player, was traded from the L.A. Lakers to the Dallas Mavericks.
