Facebook Billionaire, Sean Parker Dropping $9 Million On Wedding Decorations

Sean Parker And Alexandra Lenas
If you invested in Facebook, here's another reason to unfriend Fbook billionaire Sean Parker -- he's blowing nearly $9 mil to create a temporary backdrop for his wedding.

We've learned Parker -- who made billions with companies like Napster and Facebook -- booked the entire ultra-swank Ventana Inn in Big Sur, CA for the weekend of June 1st to tie the knot with Alexandra Lenas in an over-the-top wedding with a medieval flair.

To realize his vision ... we're told Sean hired a landscaping company to build fake ruins, waterfalls, bridges, ponds and a gated cottage in the resort's surrounding forest -- where he'll say "I do" in a ceremony fit for a king ... or Hobbit. 

All the guests will enter through a $600,000 gate, dance on a $350,000 floor, and they better stop and smell the roses ... because Parker's dropping more than $1,000,000 on plants and flowers!

Throw in a bunch more fancy overpriced decorations ... and grand total for the BACKDROP is $8.6 million. 

In case you care ... Sean hired the costume designer from "Lord of the Rings" to make dreads for his guests ... and like a yarmulke at an Orthodox Jewish temple ... you can't get in without it.
