Ashlee Simpson hosted a Winnie the Pooh-themed baby shower on Saturday.

The 'Outta My Head' singer — who is due to give birth to her first child later this month — celebrated with 35 guests, including singer-and-actress sister Jessica Simpson, her mother Tina, actress Emmy Rossum and Nicole Richie, who brought her 10-month-old daughter Harlow.

A source at the shower — which was briefly attended by Ashlee’s husband, Fall Out Boy rocker Pete Wentz — said: "She was glowing and insanely happy. Pete was so excited too!"

Guests enjoyed a feast of chicken and mashed potatoes, crab cakes, peanut butter and jelly sandwiches, jicama salad with grapefruit and a bumblebee-shaped cake before Simpson was given several gifts, including several outfits from Kitson Kids and a mini-Burton snowboard suit and matching gear.

Simpson's friends and family were only given the time and location, Los Angeles Bel-Air hotel early on Saturday morning, in order to keep it secret.
