Potty trouble for Jessica Simpson!

In NYC on Monday, the singer and designer, 30, encountered some difficulties in the ladies room at posh department store Bergdorf Goodman. Naturally, she shared a photo!

"Short girl problems," Simpson wrote beneath a TwitPic of her feet, dangling from the toilet, evidently too short to reach the floor below.

The star is in the Big Apple with younger sister Ashlee, nephew Bronx and their mom Tina to work on their tween denim line for the Jessica Simpson Collection. One thing Simpson's not addressing head-on: Web rumors speculating her pregnancy.

Simpson, engaged to former NFL star Eric Johnson for nearly a year, was snapped yesterday in NYC clutching her belly, covered up with a winter-weather poncho.
