Paris Hilton and Benji Madden have ended their nine month relationship, reports say.

Friends of the US socialite told The Sun that she decided this week that they were "too different" and had "grown apart".

The relationship was under further strain due to the amount of time Hilton, 27, has spent outside of the US filming ITV2 show Paris Hilton's New Best Friend in London.

"They are just way too different. He has helped her grow up and they want to stay friends. But essentially he's a bit controlling," the friend said.

Hilton's publicist Alanna McCarthy said that the two "remain very good friends".

The Good Charlotte guitarist recently described Hilton as the love of his life, adding: "She is my life, my heart and my soul, and is the most important thing in my life. No-one exists but her."
