Cheryl and Ashley Cole reportedly rowed over Black Eyed Peas member will.i.am before their break-up.
According to a report in The Sun, tension developed between the couple last year when Ashley told his wife that he was "sick" of the attention she was receiving from the star.
Cheryl and will.i.am worked together on the 'X Factor' judge's debut solo album '3 Words'.
Although there is no suggestion they have ever been romantically involved, recently will.i.am confessed that he is attracted to the singer in an interview published yesterday.
Cheryl announced that she had split from Ashley last month following allegations that he had been unfaithful with a number of different women.
