The glamour model is keen to start divorce proceedings as soon as possible, and will reportedly be filing for divorce on their first anniversary
On what should have been a date for celebration, the couple could instead be officially kick-starting proceedings to end their fledgling marriage.
According to The Sun, Katie's lawyers advised her that the earliest date she would be able to legally file for divorce would be next Thursday 10th February - one year since their quickie Las Vegas wedding.
By law, divorce proceedings can only start after a year of marriage, otherwise an earlier annulment can only be granted in cases of particularly 'unusual' circumstances.
'She told Alex she would petition for divorce as soon as possible, which is a week on Thursday' a friend told the paper.
'He has agreed. This is one of several significant gestures on his part'
The pair reportedly held crisis talks in Katie's Surrey mansion on Monday, during which Alex is thought to have finally agreed to end the marriage.
