Jeweler Tiffany & Co. is featuring a same-sex couple in its new engagement ad for the first time in the company's advertising history.

The black and white ad shot, taken by fashion photographer Peter Lindbergh, features two handsome men, sitting together on a New York City stoop. The men, who are actually a real-life couple, smile and lean in toward each other, looking truly happy.

The ad features two men's wedding rings next to the text, "Will you promise to never stop completing my sentences or singing off-key, which I'm afraid you do often? And will you let today be the first sentence of one long story that never, ever ends?"

The ad is part of the "Will You?" campaign that also includes six other couples. Another ad in the campaign features a couple's child with them as they get married, in an attempt to show diverse relationships.

"True love can happen more than once with love stories coming in a variety of forms," Linda Buckley, a spokesperson for the company said.

And Tiffany's want to share the moment with all kinds of couples. "The Tiffany engagement ring is the first sentence of the story that a couple will write together as they create a life that is deeply intimate and exceptional, which is the message we hope to convey through this campaign," she said.

As the 178-year-old jeweler takes a more "modern approach to love and romance," they aren't the only ones. Ads for Cheerios and Ray-Ban have already depicted gay marriage as many more Americans embrace same-sex couples' rights.
