Despite having an open relationship it is thought Dwina 'hit the roof' when she discovered Claire was pregnant.
It was revealed last week that Robin had paid out £4million to Claire and their three-year-old daughter Snow Robin.
Robin's fans will be able to pay their respects to the singer when his horse-drawn glass carriage is taken through his home town of Thame, Oxon.

At the service Dwina will read a poem that she wrote especially for today and a song written by Robin will also be debuted.
