Tessy added: "It will be a very small and intimate gathering of close family and friends. We do know that many close friends from abroad, especially UK will be missed due to Corona regulations. However, do not worry, the big wedding ceremony will be held in a few months time after baby has arrived and I am sure by then that the corona regulations should be adjusted."
As well as running a bespoke consultancy, Finding Butterflies, Tessy is also a co-founder of charity Professors Without Borders and luxury sustainable womenswear brand, Human Highness.
