The wild party in the Hamptons guarded by DRONES: Millionaire uses a fleet of robots to keep trespassers out of $1m Garden of Eden-themed 60th birthday at his vast 'Playboy Mansion' castle 

Philanthropist and banker turned musician Ivan Wilzig had a surprise guest at his naked $1million 60th birthday party in the Hamptons - a drone.

The security team at Wilzig's 10-acre Water Mill estate, dubbed the Playboy Mansion of the Hamptons, used the flying device to make sure the 700 partygoers behaved themselves and to prevent gatecrashers at the Garden of Eden themed bash on Saturday where clothing was optional.

Partygoers were handed fig leaves as they entered the celebrations and many followed the undress code, the New York Daily News' gossip column Confidential reported.

Posting to Facebook today, Wilzig, who performs as Sir Ivan, wrote: 'According to the Bible, God sees everything... But just in case he misses someone, I've got my drones.'

A source told the gossip column: 'At the end of the party, around 1am, 25 security guards hustled everyone off and several people saw two naked women in high heels walking down the highway.

'They wound up in the woods and had to be rescued.' 

The source added the e-spy was 'connected to security cameras'.

The philanthropic millionaire Wilzig a former banker who became a singer and songwriter, has thrown many a wild party in his 15,000-square-foot castle in the Hamptons, from medieval themes to super heroes.

He decided to bring in the drones after 'people kept disappearing into the woods' at previous parties'. 

'Sir Ivan hired a drone to circle the area and not only make sure that no one went missing — but also so no crashers would break in,' a source told the gossip column.

Ivan posted about his drones to Facebook on Monday saying 'according to the Bible, God sees everything... But just in case he misses someone, I've got my drones'

Ahead of Saturday's party Wilzig posted to Facebook: 'Tonight you will see the greatest lighting show in history as I turn my 15,000 square foot Castle into a 15,000 square foot birthday cake to celebrate my 60th and the success of my new single 'Imagine''

Despite the tight security, a couple of partygoers slipped by and made it to the house for an after-party.

'Ivan found them at 3am when he went to get a sandwich and yelled, "What are you doing? You almost gave me a heart attack,"' the source added.

He let them show themselves out, Confidential reported. 

'Carry on, as long as you make a little Cain and Abel,' he reportedly told them.
