The Oscar-winning actress - who recently split from Burberry model Louis Dowler - is said to be enjoying a new romance with a mystery man and the pair were spotted having a three-hour lunch together last week at exclusive London restaurant Scott's.
An onlooker said: "(Kate) looked very content. They were chatting for hours. She was in fits of giggles at one stage and then later they looked very serious together. It seemed they were having an in-depth discussion and she clasped his hands over the table. When Kate finally paid the bill, it was getting dark."
When the pair - who have known each other for years - finally left, they asked waiters to arrange for them to leave separately as they didn't want anyone to see them together.
The 'Titanic' star split from Louis in November saying she wanted some time alone following the breakdown of her marriage to director Sam Mendes in March.
Three men in just over a year! Do you think Kate should slow down and enjoy the single life for a while?
