Rihanna and Chris Brown are reportedly planning a joint hen and stag party with a cruise in the south of France.
The Sun said that the couple would embark on the two-week trip, that will also take them and their friends to Monaco and Corsica, before they tie the knot.
The cruise will begin once the European leg of Rihanna's world tour is over.
A source said: "They're telling pals it's going to be a wild joint stag and hen do ahead of them tying the knot. It will be a 24-hour-a-day party.
"It's going to be absolute mayhem. The crew are going to have to sleep in shifts."
The newspaper said Rihanna would return to the yacht Latitude, where she holidayed last year.
The couple are reported to be planning a wedding ceremony in Barbados in July.
