Chelsea Clinton and hubby Marc Mezvinsky are smiling off rumors claiming the couple is close to calling it quits.

While attending the black tie opening gala for Set In Style: The Jewelry of Van Cleef & Arpels at NYC's National Design Museum, the couple walked arm in arm hoping to squash reports of a troubled marriage.

Bill Clinton's 31-year-old daughter, wearing a plunging neckline, flashed us her pearly whites while holding on tight to her man.

As for whether the couple are thinking of having kids, they aren't talking, but can't say the same for Chelsea's mom. In a recent interview with Harper's Bazaar, Hillary Clinton told the mag, "Well, no pressure, because I don't want to be one of those kinds of mothers. But obviously, someday, I'd love it.'

Let's hope they go the distance!
