LL Cool J has written a letter to President Barack Obama offering him words of advice and support.

The rapper was one of countless musicians who endorsed Obama in his Presidential campaign and now he has given him some kind words just weeks into the presidency.

He writes: "The next chapter of your life has begun. The toughest decisions you will ever have to make lie in front of you. Decisions that will require you to choose between integrity and necessity to enact the promises made to millions of people, and recognise a change in perspective that will sometimes make those promises impossible to keep. Only you will be able to make those choices.

"You have shifted the cultural paradigm of America, but now you have to live up to the ideal that fostered the shift and ensure that the paradigm doesn't shift back. You must deliver."
