Nine-months pregnant Jessica Simpson and her sister Ashlee were bridesmaids in the wedding of their friend Lauren Zelman to actor Bret Harrison on Saturday evening.

The 31-year-old, who’s a bride-to-be herself and due to be married to ex-footballer Eric Johnson after their baby arrives, was walked down the aisle by her fiancé. The Simpson ladies wore pink wrap gowns with a tie at the side and carried bouquets of white, pink and peach colored roses and peonies.

The wedding took place at the Parker Palm Springs Hotel.

Also involved in the bridal party was Ashlee Simpson’s adorable son Bronx who had the very important role of ring bearer during the ceremony.

Also in the wedding party were Adam Brody and Josh Schwartz, who walked down the aisle with Ashlee.
