Be upfront and honest. Approach him calmly and at the right time. The right time should be when you know he is calm and relaxed and in a setting you know he will be comfortable. Beyond that it's just a matter of being upfront with him and telling him everything you know.
But don't expect him to adjust to it right away...there might be a shock period, but if you are calm and understanding he should get over that quickly and hopefully you will be able to plan with him how both of you want to handle the whole thing.
