Nicole Richie craving pickles

Nicole Richie is craving pickles.

The pregnant star, who already has a 16-month-old daughter Harlow, begged her partner Joel Madden to buy her some brine-soaked savoury snacks during a family day out recently.

A source said: "After enjoying lunch with Harlow at Beverly Hills deli Nate 'n Al, Nicole told Joel she wanted some pickles to go. Joel popped back in the eatery and came out seconds later with the goods."

However, Joel was forced to return to the cafe because Nicole was upset with him for buying the wrong type of pickle. The source added to the National Enquirer magazine: "Nicole told him, 'These aren't the right ones,' and sent him back. Joel finally got the order right the second time round."

Nicole is due to give birth in August and it was recently claimed the couple are expecting a boy after the pair were spotted buying blue baby items.

A source said: "Joel bought water-based paint for the nursery and - surprise, surprise - it's blue! Plus, Nicole recently ordered some plush animals and infant toys, and everything just happens to be blue."

Nicole, 27, has also been referring to her unborn baby as "he".
