The mystery of Biel's bump! Jessica sparks rumours she's expecting her first child with Justin Timberlake ...flashing her tum in LA

They recently enjoyed their second wedding anniversary, and by the looks it, now there could be another celebration on the cards.

Jessica Biel has sparked rumours she's expecting her first child with Justin Timberlake, after stepping out this week revealing what appeared to be a baby bump.

The 32-year-old actress was pictured on Wednesday shopping with a pal at the American Party Store on Vine in West Hollywood.

 

Making sure not to do any heavy lifting, Jessica's business partner and stylist Estee Stanley instead carried a huge disco mirror ball for the star as they left the store together. 

Wearing a pair of tight-fitting jeans and a chunky knitted scarf, Jessica's unbuttoned shirt revealed a mystery bump as she headed home.

MailOnline has reached out to a representative for the actress who has so far been unavailable for comment.  

Jessica and Justin, 33, have certainly been open about their plans to start a family together.
