Singer and vegan Jessica Simpson is expecting her second baby

Singing superstar Jessica Simpson has announced that she’s expecting her second baby.

The celeb revealed her news on Twitter by posting a picture of her seven-month-old daughter Maxwell on a beach with the words “BIG SIS” written in the sand next to her.

Subtle. 

She captioned the picture with “Merry Christmas from my family to yours!”

Jessica, who’s engaged to Eric Johnston, has previously been reported to be following a vegan diet and has been involved with a number of environmental and humanitarian projects.

A few years back she won a Chrysler Crossfire sports star at the MTV Video Music Awards, but exchanged it for a minivan which she donated to an orphanage.

Eric is a dedicated vegan and Jessica has apparently taken vegan cooking classes in order to prepare his favourite meals.

She also uses and promotes organic clothing. Better get some more natural baby products and eco-nappies in for the next one, Jessica! Beaming Baby Biodegradable Nappies are Vegan Society approved!
