For those of you who were hoping that the window was still open to snatch up Pippa Middleton, 29, since her split from boyfriend Alex Loudon last year and her is-she-isn't-she string of possible suitors since, who included her longtime friend George Percy, it looks like you might be out of luck. Middleton has been spotted out several times in the past month with investment banker James Matthews, 37, the brother of U.K.'s Made in Chelsea reality star, Spencer Matthews.

"They have been out together a few times," a source for Matthews told Us Weekly. "It’s very early days but James really likes her. She’s a smart girl who has her head together. They have a lot in common.”

While Middleton has been enjoying swanky dinners with Matthews, she has also been promoting her new party-planning book, Celebrate, which hits bookstores in the U.S. today.
