Michelle Keegan is all-too-familiar with photoshoots, having worked with Revlon and modelling her Lipsy fashion collection for the past few years.However it isn't the opportunity to get glammed up...
The French magazine Paris Match published photos of the duo splashing around in the turquoise waters of the Caribbean.
Alexandra, known as Sasha, and India are fifth and sixth in line to the throne respectively, following their cousins Jacques and Gabriella - the twins of Princess Charlene and Prince Albert.
But they have no royal titles and live a rather more low key life compared to their cousins who reside at Monaco's royal palace.
Prince Albert's sisters are Caroline, Princess of Hanover, and Princess Stéphanie.
In July 2011, Prince Albert married Charlene Wittstock. While Prince Albert's real estate does not include the Prince's Palace of Monaco, it does include holdings in the Société des bains de mer de Monaco, which operates Monaco's casino and other entertainment properties in the principality. He has ancestry from Ireland, Britain, the United States, Germany, France, Belgium, and Monaco.
