Kim Kardashian certainly wasn't keeping her mouth shut today!

The pregnant reality star left the studio on Thursday afternoon and was looking especially curvy in her bodycon maternity wear. Nori's mom kept warm on the chilly Los Angeles day with a black naval-style overcoat.

It's possible the cold weather got her mouth moving because she was all talk when our cameraman asked Kim if she was worried about latest news that her sister Khloe Kardashian was no longer on her estranged spouse Lamar Odom's hospital visitor list.

In response, Kimbo said, "I'm worried about people believing the rumors."

Kim rarely comments on bad press so we think it says something that she's speaking out, trying to set the rumor straight about her sister's relationship with the basketball player.

While the Kardashian/Jenners are still stuck in some Khlomar drama -- the whole fam is gearing up for mom Kris Jenner's 60th birthday party, which will be star-studded soiree on Friday night in West Hollywood.
