After an engagement party celebrated with the Monaco royal family's customary savoir faire, Andrea Casiraghi and Tatiana Santo Domingo are back in Monaco.
Princess Caroline's son and his fiancée touched down on dry land following a few days cruising the Cote d'Azur on Pacha III, the Grimaldi's family yacht.
A certain amount of excitement will have greeted their arrival, not just because of the betrothal but also because Tatiana may be pregnant.
Tatiana, the granddaughter of the late Colombian mega-mogul Julio Santo Domingo, worth $6bn, is known for her love of flowing bohemian clothing.
In fact, she often uses her twitter feed to show off loose peasant style garments that she has picked up from artisans around the world, for her business Muzungu Sisters.
Even so, media comentators have noted what appears to be a growing bump.
Any baby born to the couple would be third in line to the throne given that Prince Albert, 53, does not have any children with Princess Charlene.
The laidback lovebirds probably don't have their minds on the succession, they will be too busy enjoying this special period before becoming husband and wife in 2013.
