Britney Spears was kept in the dark about her 16-year-old sister's pregnancy.
After a shopping spree at Lisa Kline last night, Brit was bombarded with questions about Jamie Lynn - and Brit denied the news!
After ignoring the question and smiling for paparazzi, Brit finally told X-17, "My sister is not pregnant."
The paparazzi assured Spears that she was, to which Britney responded "Whatever."
News of Jamie Lynn's pregnancy broke yesterday afternoon.
