A representative for soccer superstar David Beckham has dismissed allegations linking him to a U.S. couple's divorce, branding the claims "fantasy".

Millionaire lawyer Kambiz Shabani accused his wife Shery of having a fling with the sportsman which contributed to their marriage breakdown.

Jewellery-maker Shery, whose children attend the same school as Beckham's sons in Los Angeles, has denied her estranged partner's allegations, stating, "This has nothing to do with David. It is my husband's craziness. He has accused me of having affairs, most often with David Beckham (which is untrue)."

Beckham's spokesperson has also been quick to distance the star from the court paper revelations, saying, "This is a tale full of fantasy."

It is the second time Victoria Beckham's husband has hit the headlines in recent weeks - his legal team filed a multi-million dollar lawsuit last month against former prostitute Irma Nici, who claims the soccer star used her services twice in 2007. Beckham's lawyers have also targeted the company behind the magazine which published the claims in the U.S.
