William speaks about love life

The prince rehearsed with the African band he invited to his party

Prince William has celebrated his 21st birthday with an African themed party at Windsor Castle.

In the second instalment of an interview with the Press Association to mark his coming of age, the prince reflected on life and the future.

On romance:

"I don't have a steady girlfriend. If I fancy a girl and I really like her and she fancies me back, which is rare, I ask her out.

"But, at the same time, I don't want to put them in an awkward situation because a lot of people don't quite understand what comes with knowing me."

He added: "There's been a lot of speculation about every single girl I'm with and it actually does quite irritate me after a while, more so because it's a complete pain for the girls."

On media attention:

"The media can be tricky at times but so can most people.

"But it's something that I want to handle with the most maturity I can.

I want people to call me William - for now

On his royal title

"So it is difficult but it's not impossible.

"The way it's been handled so far, particularly to do with me, has been amazing from both sides, St James's Palace and the media."

On his title:

"I am and always will be an HRH. But out of personal choice I like to be called William because that is my name and I want people to call me William - for now.

"I was HRH Prince William as soon as I was born. But I don't want all the formalities because they're not needed for the time being."

On his duty:

"All these questions about do you want to be king? It's not a question of wanting to be, it's something I was born into and it's my duty."

On the pressures of being heir:

She's a huge role model for me - she's incredible

On the Queen

"Sometimes I do get anxious about it but I don't really worry a lot. I want to get through university and then maybe start thinking seriously about that in the future.

"I don't really ever talk about it publicly. It's not something you talk about with whoever."

On the future of the monarchy:

"Modernisation is quite a strong word to use with the monarchy because it's something that's been around for many hundreds of years.

"But I think it's important that people feel the monarchy can keep up with them and is relevant to their lives."

He added: "It would be dangerous to look a long way ahead and predict changes in the monarchy."

On what the monarchy means:

"We are all human and inevitably mistakes are made. But in the end there is a great sense of loyalty and dedication among the family and it rubs off on me.

"Ever since I was very small, it's something that's been very much impressed on me, in a good way.

"People say it's not ambitious, but it is actually quite ambitious wanting to help people."

On the Queen:

"I think of the Queen first and foremost as my grandmother and to me that's important.

"She's a huge role model for me - she's incredible - and in the family she's one of the biggest role models I have, along with my father."

He added: "What she's done for this country is amazing."
