A Spanish actress is threatening to sue Victoria Beckham after the former SPICE GIRL allegedly called her "a piece of s**t".

The singer hit out after rumours ANA OBREGON, 50, had set her sights on Beckham's soccer star husband DAVID, who plays for Spanish team Real Madrid.

Beckham, 31, reportedly confronted Obregon - who has been linked with a number of younger men - after they bumped into each other at a gym.

Obregon's lawyer JAVUER SAAVEDRA says, "The altercation initiated and protagonised by Mrs Victoria Beckham is absolutely unjustified, absurd and disproportionate."
