Some people just can't tell those Kardashian sisters apart.
Kim Kardashian wrote on Twitter Monday that she was congratulated for being pregnant. The only problem: big sis Kourtney is the one expecting.
"Some woman just came up to me & said congrats 4 being pregnant! I know she thought I was Kourt but rude! Do I look 8 months preggo?" Kim moaned on Twitter.
The reality star, 29, had the encounter after visiting a doctor's office.
"I'm not feeling so good today. I have a cold & Kourtney made me go 2 the Dr. 2 check 4 Swine Flu!" she wrote. "I'm fine Dr. says, NO SWINE."
