AceShowbiz - Pregnant pop punk Pink is struggling to control her hormones - she became embroiled in a car park bust-up during a recent shopping trip after becoming grouchy. The "So What" superstar and her husband Carey Hart are set to become parents early next year and the feisty star admits her cravings for sour food have turned her into a raging mess - as one fellow shopper witnessed on a trip to U.S. retailer Bed Bath and Beyond.

Pink tells "The Billy Bush Show", "(She's craving) Sour Patch Kids, or Sour Skittles, sour anything. Maybe that's a testament to myself. I got into a fight at Bed Bath and Beyond. I have the rage! There was this man, and he was very rude. Something about Bed Bath and Beyond brings out the worst in people. This man wanted a parking spot and he honked at me and he was literally an inch from my ear drum... I (went over to his car) and he acted like he couldn't see me, and then he acted like he couldn't speak any English."

"I think he realized I was going to kill him! And the poor bag boy (who) was helping me with my stuff wanted to be invisible."
