The former Spice Girls singer - who was known as 'Posh Spice' during her time in the girl group - is devastated for her close pal following the 'Desperate Housewives' actress' announcement last week she is separating from the basketball player.
The 36-year-old star is determined to bring a smile back to Eva's face and is organising a girls-only night out for her.
A source told the Daily Star newspaper: "Victoria has rounded all the girl troops in their inner clique so they can have some girly time and relax. Posh has given her some sexy VB dresses to cheer her up and is planning a night out for Eva with all their celeb friends."
Victoria has also invited the 35-year-old actress to her Los Angeles home to spend Thanksgiving Day (25.11.10) with her and her family - husband David Beckham and sons Brooklyn, 11, Romeo, eight, and five-year-old Cruz.
The source added: "Victoria has asked her over for dinner and wine to cheer her up."
Victoria and David struck up a close friendship with Eva and Tony when they first moved to Los Angeles in 2007. The former couple helped the British stars settle into Hollywood.
The screen star filed papers to dissolve her three-year marriage last Wednesday (17.11.10), citing "irreconcilable differences" as the reason for the break-up.
The 28-year-old sportsman filed his own divorce papers in Bexar County, Texas, on Friday (19.11.10), stating the "marriage has become insupportable because of discord or conflict of personalities between Petitioner and Respondent".
