Trista and Ryan Sutter will celebrate their fifth wedding anniversary with a christening.

Princess Cruises has announced that The Bachelorette first-season lovebirds will christen their newest cruise ship -- Ruby Princess -- on November 6 in Fort Lauderdale, FL. 

Trista and Ryan will subsequently celebrate their fifth anniversary on December 6 during the Ruby Princess' inaugural season, which will be themed around "romantic moments and milestones."

"We're incredibly honored to be invited to be the godparents of Ruby Princess," said Trista.

"It's hard to believe that it's been five years since we got married. 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. We are so excited to be part of this once-in-a-lifetime opportunity!"

Trista served as the object of affection on The Bachelorette's early 2003 first installment, and more than 30 million people watched her choose Ryan as her man during the finale. 

Ten months later ABC aired a three episode series that detailed the events leading up to their wedding ceremony and over 17 million viewers watched the couple exchange vows on ABC's Trista & Ryan's Wedding finale broadcast.  They welcomed their first child -- Maxwell Alston Sutter -- late last August.

"Princess Cruises has long stood for romance and reconnection, and so we're delighted to have Trista and Ryan christen Ruby Princess as they celebrate their fifth wedding anniversary," said Princess Cruises executive Jan Swartz.

"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."

The 3,070-passenger Ruby Princess' inaugural season will make seven-day weekly sailings from Fort Lauderdale to the Western Caribbean.
