Yes, celebrities frequently go on cruises, though they often do so for work or through high-end "discreet" bookings. Many stars participate in "Themed Cruises"—for example, the Star Trek Cruise often features actors like George Takei or LeVar Burton. Other celebrities, such as Gwyneth Paltrow, have partnered with lines like Celebrity Cruises for "Goop at Sea" wellness retreats. For their private vacations, A-list celebrities like Oprah Winfrey or Bill Gates tend to charter private mega-yachts, but they are occasionally spotted in the most exclusive "ship-within-a-ship" enclaves like The Haven on Norwegian or The Yacht Club on MSC, which provide private butler service and secluded pool decks away from the general public. Additionally, British icons like Olly Smith or Dame Shirley Bassey are frequent guests or performers on lines like P&O and Cunard, maintaining the long-standing tradition of high-profile "ocean liner" luxury travel.
