Erica Packer's 40th birthday has culminated in A Midsummer Night's Dream-themed feast hosted by Borat.
The model and singer - and James Packer's former wife - celebrated her milestone birthday at a private property close to the exclusive ski resorts of Aspen with three days of festivities attended by her close friends Orlando Bloom, Sarah and Lachlan Murdoch and Vogue Australia's fashion director Christine Centenera.
A Borat impersonator wearing the character's famous lime green "mankini" was on hand to help Erica, known as "Eri" to her friends, with her speech.
"In advance I'm so, so sorry. But to tell you the truth I was a little nervous to jump up here and speak to you all alone. So we prepared a few lines," Packer said.
"And snorted them all," the Borat impersonator interrupted as Packer blanched.
Packer's brother Billy Baxter and sister Jo Hunter were on deck as were a handful of friends she has made since relocating to Los Angeles following her rumoured $100 million divorce in 2013.
While her ex-husband and father to her three children was not present at the party, the Packer family were represented by matriarch Ros, wearing what appeared to be a foot brace, his sister Gretel and niece Francesca.
James has made a habit of skipping out on family birthdays. He was a no show at Gretel's intimate 50th celebrations held in Sydney last year.
Erica Packer, wearing a black shift dress and $1700 electric-blue lace Balenciaga boots, hosted welcoming drinks earlier in the week on a patio in the shadows of the Elk Mountains.
The party kicked on later with a medieval inspired dinner catered by celebrity chef Francis Mallmann, the Argentinian cook known for forgoing modern cooking techniques and instead using sand, hot stones, leaves and ashes.
Mallman presented Packer with a modest birthday cake complete with just six candles while guests made like Cersei Lannister and sipped $120 Nicolas Catena Zapata 2009 malbec (decanted from six-litre methuselahs) from rustic gold goblets.
???The birthday girl wore a red ruffled and sequined ensemble complete with a head-dress containing more baby's breath than a 1980s wedding party.
Before the sun went down the Packer children played with Bloom's toy poodle, Mighty, as lamb carcasses roasted on iron crosses and line-caught salmon in salt crusts cooked in hot coals.
Signs reading: "No Go Home Zone" were placed around the party as guests were entertained into the night by several DJs, including Samantha Ronson, and warmed themselves around fire pits, proving you can take the girl out of Gunnedah ...
