Oh my! TV Land sitcom The Exes is about to stage a wedding for the ages in its season finale, and it’s not what you think.

ETonline exclusively premieres a sneak peek at Wednesday’s season closer, appropriately titled “The Wedding,” with Holly (Kristen Johnston) taking the plunge – except she doesn’t have a groom thanks to her breakup with the congressman.

So, how is this going to work? Simple: Holly will marry... herself!

While Holly thinks it’s the only feasible plan, her friends aren’t 100 percent sold. But when she sends Evites to her one-woman wedding, reality sets in that Holly actually may go through with this.

“I know this whole thing might seem unusual, but I’ve spent my entire life looking for a man to marry thinking that’s what I needed to feel complete until I realized I don’t,” she says. “I’m happy with who I am. I value who I am and I wanted to celebrate that in front of my friends and family.”

Only, what kind of wedding did she have in mind? Watch the rest of the scene to see it all play out!

The Exes airs Wednesdays at 10:30 p.m. on TV Land.
