Trista and Ryan Sutter will christen the Ruby Princess on Nov. 6 in Fort Lauderdale.
The Sutters met on ABC's reality series, "The Bachelorette," and will celebrate their fifth wedding anniversary this fall, Princess Cruises said.
They are the first and only couple from "The Bachelor" or "The Bachelorette" to get married.
Princess said the 3,070-passenger ship's inaugural events will be themed around "romantic moments and milestones," in celebration of National Romance Week.
"Princess Cruises has long stood for romance and reconnection, and so we're delighted to have Trista and Ryan christen the Ruby Princess as they celebrate their fifth wedding anniversary," said Jan Swartz, Princess' senior vice president. "While slightly unconventional, their courtship and marriage was exciting to watch as it unfolded, and we think their fascinating love story epitomizes our inaugural theme of celebrating romantic moments and milestones."
Trista Sutter said, "This is a wonderful way to celebrate our wedding anniversary, and also to remind people about the importance of marking not only the key milestones in a relationship, but also making time to incorporate romance into our everyday lives."
