Pictures have emerged of the actress during her wedding celebrations with movie producer husband Trevor Engleson in 2011.
Wearing a skimpy, yellow polka-dot bikini and baseball cap, Miss Markle can be seen taking part in a wheelbarrow race. The pictures, first published in a US magazine, show her donning a pair of sunglasses next to a table with bottles of local lager, Red Stripe.
She reportedly joined in drinking games with guests at a Jamaican hotel the day before she was married.
The pair tied the knot at the Jamaica Inn in Ocho Rios in front of about 100 guests after dating for seven years.
They had a beach barbecue and were also lifted in the air on seats during a traditional Jewish ‘chair dance’.
But the couple separated in 2013 and divorced in August that year, citing irreconcilable differences.
Miss Markle, 35, has officially been dating the 32-year-old royal since June.
Last week, the couple were said to have ditched the hustle and bustle of London for the remote town of Tromso on the Norwegian fjords.
