FIRST LOOK: Sam Branson And Isabella Calthorpe's Wedding Pics
Filed under: Have you seen?
And it appears it was an all-white affair as the bride wasn't the only one to wear the traditional bridal colour. Sir Richard's son decided to match his new wife's attire with a white tux as the pair said "I do" at the Branson game reserve in Kenya.
Guests including Princesses Beatrice and Eugenie, Isabelle's sister Cressida Bonas (who is currently dating Prince Harry), Natalie Imbruglia, and TV professor Brian Cox attended the glamorous five-day celebration.
And Isabella looked stunning in her romantic, frothy lace strapless Monique Lhuillier dress as she married the heir to the £3.4 billion Virgin fortune under a sacred tree on a hill overlooking Sir Richard's private game reserve Ulusaba, on the edge of the Kruger National park.
Isabella told Hello!: "To me, going on safari is one of the most incredible experiences you can have.
"So, for our families and friends to be able to share in something we love so much as part of our wedding celebrations is wonderful."
