However, their friendship has fizzled out and turned sour as the cracks appeared in Holmes' marriage to Tom Cruise which eventually ended up in divorce.

Meanwhile, reports are claiming that the newbie to the designer world Katie Holmes is planning to use the current publicity that surrounds her high-profile divorce from Hollywood superstar Tom Cruise as an advantage to steal the limelight from the professional Victoria Beckham.
