"The United Nations issued a shocking report on the environmental damage being done by livestock. I became a vegetarian for health reasons. Then I found out about the awful animal abuse in factory farms and dairy herds and became a vegan. The easiest and most effective way of cutting our contribution is to change our diet and go vegan."
Meanwhile, Heather is reportedly in trouble with her local council after allegedly starting work on a swimming pool without permission.
Planners had visited her £3 million property in Brightling Road, Sussex, to check she had taken down a marquee which had been erected without permission when they noticed the alleged "unauthorised development".
A Rother District Council spokesman said: "The marquee appears to have been dismantled.
"Apparently there is a swimming pool and we have invited a planning application for it. This will then be considered in accordance with the normal planning process.
"If an application is not received within the next month then a report will be prepared for the council's planning committee at which time consideration will be given to taking appropriate enforcement action against any unauthorised development."
