When you're trying to launch your pop career it helps if you have famous sisters to appear in your videos... especially if it's something of an erotic display.

Hollywood film star Penelope Cruz and her sister Monica agreed to a highly risque performance to accompany their 22-year-old brother Eduardo Cruz's new single.

The video for Cosas Que Contar starts with a scene where the Cruz sisters dub a lesbian porn film. They then suck suggestively on lollypops and writhe around in bikini's and ripped stockings.

The actresses whisper in Eduardo's ears and Penelope is even seen in a lesbian clinch with Argentinian actress Mia Maestro.

Spain is proud of their famous 'favourite daughters' who have designed a fashion line for high street store Mango. But there is always frantic speculation about their love lives in the Spanish press, which the footage has fuelled.

One Spanish commentator unkindly noted that Eduardo's singing talent varies "in inverse proportion to the keenness of young heterosexuals to see the Cruz sisters".
