A video of the event, which was held on March 18, has been released showing giant red letters spelling out baby, a roof full of over-sized lanterns, a collection of gifts, a knitting station, a buffet of food and an ice-cream cart.
The guests included her sister Ashlee and celebrity friend Jessica Alba who took daughter Haven along with her.
Jessica’s fiance Eric Johnson also shunned tradition and attended the shower as well, sitting beside his wife-to-be to open gifts.
Due any day now, Jessica is keeping fans up-to-date on her pregnancy via twitter. On April 22 she wrote: "To everyone who keeps congratulating me on the birth of my baby girl...I'm still pregnant!! Don't believe what you read ladies and gents."
Days later she added: "I just woke up from a dream that I wore a leopard caftan in the hospital. Fabulous!! Now I need to find one!"
