As the celebrity offspring of one of the world's greatest ever rock stars, Mary McCartney has a tough act to follow.

The 42-year-old daughter of Paul and Linda McCartney showed that being passionate about animals runs in the family.

Sir Paul's first born child had almost all of her famous family down in London to support her as she launched her very own vegetarian cookbook, earlier today.

With his wife, Lady Nancy McCartney, Sir Paul, 69, beamed with pride as Mary continued to follow in the footsteps of her late mother Linda.

While Nancy covered up in a long light brown colour jacket with silver trousers, Sir Paul kept it formal in a black suit and a blue shirt.

The proud father-of-four, who is a long standing vegetarian, posed for pictures with the book and was seen flicking through it.

Stella McCartney, 40, showed support for her older sister and looked as stylish as ever in an all black outfit.

The British fashion designer wore a plain trouser suit with smart black shoes and a pink grandad collar shirt.

Mary also looked good in a silver blazer which she teamed with a pair of faded black jeans and green heels.

Although she has already been a successful photographer like her mother once was, she has decided to release a collection of recipes that are inspired by Linda.

She said: 'My cook book comes from my life growing up as a vegetarian and watching my mum cooking in the kitchen.'

'This book is a collection of my recipes and photographs and stories throughout the years really to inspire vegetarian cooking.'

She added: 'It’s been a labour of love and I hope that you enjoy.'

Her mother wrote several vegetarian cookbooks and also had her own food products before dying of breast cancer at the age of 56 in 1998.
