Pregnant Victoria Beckham denies using gender selection treatment

It's no secret that Victoria and David Beckham are desperate for a baby sister for their three boys, but have denied claims that they used gender selection treatment to pick the sex of their new arrival.

Reports are abuzz that the couple might have paid for a technique by a Los Angeles clinic, where an embryo is screened outside the womb and put back only if it is the preferred sex, reports the Daily Star.

"David and Victoria would love a sister for their sons Brooklyn, Romeo and Cruz," said a source.

"Lots of people in LA are suggesting they may have had the gender treatment," the source added.

The soccer star and the ex-Spice Girl, however, insisted that they have not chosen the 'family balancing' technique.

"They do not know the sex of their unborn child," said Victoria's spokesperson.
