Situated on top of a hill, the 13.5 acre property is discreetly hidden and would have made the perfect rendezvous for the President and Monroe's illicit trysts

The Californian house where it is believed that Marilyn Monroe and President Kennedy once conducted their illicit affair has gone on the market for $12 million.

Forty miles outside Los Angleles, 9361 Farralone Avenue, in Chatsworth was once sub-let by Monroe and Kennedy's mutual friend Frank Sinatra in the 1960's.

While Monroe was a regular guest at the 'Rat-Pack' leader's minimalist steel and glass home, rumours abound that President Kennedy was also a frequent visitor relying on his singing friends discretion to conduct his extra-marital trysts.

The remote hill-top home would have made the perfect location for Kennedy and Monroe to carry on their alleged affair away from prying eyes and the property has been described by agents handling its sale as like being 'on top of the world' according to MSNBC.

If the walls of 9361 Farralone Avenue could talk they would have some gripping tales to tell, as the four bed-roomed home has been the scene of many a Hollywood glamour night.
