Khloe Kardashian Talks Pregnancy Problems

Countless false rumors have had Khloe Kardashian briefly pregnant, but even though she keeps shooting them down, it's not as if she isn't trying.

The reality star, who just last month again denied rumors that she was with child, talked to Us Magazine about her apparent problems conceiving with husband Lamar Odom.

"If it happens, it happens," she told the magazine. "It takes time, I guess... I don't know what the problem is."

She batted rumors away multiple times in January, in fact, saying that she had gained "love weight," instead of baby weight. She said the same thing in June.
