The royal - who was previously known as Kate Middleton - wants to see her brother-in-law settle down, so has asked his cousins Princess Beatrice and Zara Phillips to find a suitable partner to help him get over his ex-girlfriend Chelsy Davy.
A source told Now magazine: "She's planning to sit down with Bea and Zara to go through a list of people they know to see who might be a good fit for Harry.
"If he was the kind of guy that didn't care and wanted to play the field, then Kate wouldn't be putting so much effort into it. But he's serious about settling down."
Prince Harry recently revealed he has always wanted children, but just needs to find the right woman who is willing to take on the life of a royal.
He said: "I've longed for kids since I was very, very young. And so...I'm waiting to find the right person, someone who's willing to take on the job."
