But it seems he has learned somewhat of a lesson about occasionally choosing a different restaurant to dine at.
The art mogul was pictured eschewing Scott’s in Mayfair yesterday for a local Italian eatery instead, where he ate alone.
The monochrome number featured delicate bow embellishment as well as a subtle, cut-out print and frayed hemline.
The outing marked the third time they have been to the restaurant together in the past couple of weeks.
There has been no official confirmation of a romance between the pair, who are both divorced.
Trinny Woodall and Charles Saatchi have sparked rumours that romance may be on the menu after the pair have been spotted on a string of dinner dates.
The TV stylist was pictured driving away from Scott's restaurant in London with 70-year-old Charles in the back of her car.
