Jessica Simpson plays Bridesmaid

With her first baby due to be born any day now, Jessica Simpson hasn't had much time to plan for her wedding.

But yesterday she finally managed to walk down the aisle with her man by her side.

However, she wasn't about to tie the knot to Eric Johnson but play bridesmaid to one of her closest friends.

Bumping along: Jessica Simpson, whose baby is due any day, waddled down the aisle at a friend's wedding with fiancé Eric Johnson by her side

But she very nearly upstaged the bride as all eyes were on her massive stomach as everyone waits with baited breath for her to finally have her baby.

Jessica, 31, certainly looked radiant in her pink halterneck dress as she joined the ceremony at the Parker Palm Springs Resort in California.

She was joined by her younger sister Ashlee at the sunset wedding of their friend and former assistant Lauren Zelman to Reaper actor Bret Harrison.

Ashlee's three-year-old son Bronx acted as ring bearer and one eyewitness told People: 'He broke down in tears several times, but Ashlee was great and kept making him smile again.'
