In another message Prince William left for Kate "Babykins" Middleton, he says:

Hello baby, it's me. Sorry I did not ring you earlier and tell you what I was doing. Been a bit of a nightmare day. I think I would just about be finished in a minute. It has just gone six but I don't think I will be able to leave here til about seven. I have got stuff here to do, bits and pieces, but I should be able to leave at about 7 at the least. Crack on with what you have got to do and don't worry about me. I will give you a buzz later. I always thought you were going to the gym. Hopefully I can come and see you. I will give you an update. Planning on definitely coming out, hopefully by sevenish, so I will be with you by quarter to eight at the latest. Hope that's all right, baby. I can't wait to see you. Lots of love and I'll speak to you later.

Prince William was such a doting boyfriend - and we're sure he makes an even better husband!
