Details of Chelsea Clinton's extravagant wedding are starting to emerge, with estimates of the cost hitting a staggering £3m.
The 30-year-old is marrying her fiance, Marc Mezvinsky in the small town of Rhinebeck, New Jersey, this weekend.
And the setting will be the gorgeous country mansion owned by millionaire John Jacob Astor IV.
Aerial photographs show the huge white tents that have already been set up in the grounds of the sprawling estate.
No expense has been spared with the equivalent of £6,400 being spent on each of the 500 guests.
According to reports a whopping £320,000 is being spent on flowers while her dress, which is rumoured to have been designed by either Vera Wang or Oscar de la Renta, is thought to cost £16,000.
Such a high profile event obviously calls for tight security, the cost of which is said to amount to £130,000.
It's also been reported that Oprah Winfrey, Sting and Trudie Styler will be among the celebrity guests attending.
One VIP who won't be going is President Barack Obama.
"I was not invited to the wedding because I think Hillary and Bill, properly, want to keep this thing for Chelsea and her soon-to-be husband," he said on ABC's 'The View'.
"You don't want two presidents at one wedding. All the secret service, guests going through (metal detectors), all the gifts being torn apart," he joked.
Whoever is on the guestlist, it looks like set to be the wedding of the year.
