Middleton, 29, has been spotted going out on several dates with James Matthews, 37, the U.K.'s Daily Mirror reports. Kate Middleton's younger sister was photographed having dinner with the handsome investment banker at the Queen's Club tennis center in West London earlier this month.
"They have been out together a few times," a source close to Matthews tells Us Weekly. Matthews is the brother of U.K.'s Made In Chelsea reality star Spencer Matthews, and the chief executive of Eden Rock Capital Management Group.
"It's very early days but James really likes her," the source adds of the world-famous royal bridesmaid, who has been promoting her new entertaining book, Celebrate. "She's a smart girl who has her head together. They have a lot in common."
The twosome were photographed again on Oct. 29 while stepping out together on in London for a dinner date. Middleton dressed up for the occasion in a black dress, lace jacket, black tights and heels.
