Barcelona star Gerard Pique and his partner Shakira are reportedly being blackmailed over a sex tape.

The news comes amid an investigation into Real Madrid star Karim Benzema, who is alleged to be complicit in a sex-tape scandal involving his France teammate Mathieu Valbuena.

According to Diario Vasco, Pique and his popstar girlfriend Shakira are facing a similar blackmail plot as a former employee is said to be threatening to leak a "home video with high erotic content" featuring the couple.

It has been reported that the individual is demanding a "large sum of money" from the pair, who are parents to sons Milan, two, and 10-month-old Sasha.
