We thought we'd seen all the unlikeliest celebrity friendships in the book.
And now we have another couple to add to this surprising list of starry pals.
But what do Holly, 29, and Nancy, 51, actually have in common? Maybe it's a shared love of designer dresses, a penchant for large diamonds or perhaps a thirst for celebrity parties that binds them together? Or maybe it's just the fact that they both pulled on their dancing shoes for Strictly not so long ago.
Either way, the unlikely duo were more than happy to pose for pictures alongside Holly's hubby Nick in the glamorous surroundings of the Haymarket Hotel. We can only imagine what they chatted about over champagne and canapes.
Check out highlights of Holly's no-expense-spared wedding to Nick in our video - now that is a talking point.
