Loos was born in Madrid, Spain, the daughter of a Dutch diplomat and an Anglo-Spanish mother. Growing up, she was privately educated. After moving back to Madrid in 2002, Loos worked for an American investment bank, looking after bankers.

When former England football captain David Beckham moved to Real Madrid, Loos became his personal assistant during the transition period, alongside SFX agent and former Australian international Andy Bernal, who spoke Spanish fluently.

Beckham and Loos worked closely together both professionally and socially[1] and Loos claimed that she became an "alternative wife". Victoria Beckham was not initially happy in Madrid, and wanted to develop her UK music career, so she spent much of her time in England. Loos claimed this resulted in Beckham becoming bored, leading them to spend almost all their time together socially, and a four month affair was the alleged result. [2].

Loos sold her story to the News of the World tabloid newspaper in April 2004, claiming that they had had a whirlwind affair that included text messages of a sexual nature - those were later published although not in any way proven to be real. Further revelations covered Victoria Beckham. The story generated a huge amount of publicity in the tabloid press, launching Loos`s career as an ephemeral celebrity.

Shortly after the newspaper coverage of her relationship with David Beckham, Loos came out publicly as bisexual, saying "I am indeed bisexual and have been ever since I was a teenager"[3]. In 1999 while in London, she had a series of lesbian lovers, including media personality and glamour model Abi Titmuss and estate agent and TV presenter Emma Basden with whom she would enjoy a long term relationship. Loos boasts about her sexual prowess, especially her ability to "turn" heterosexual females into lesbians [4].

In the period before Celebrity Love Island, Loos had her breasts enlarged from 34C to 34D. During the transmissions of Celebrity Love Island in May 2005, Loos kissed Abi Titmuss and then cuddled up to Calum Best in the Love Shack.

In 2005, to protest against America`s laws on gay marriage, Loos "married" American fashion model Jenny Shimizu for the TV program Power Lesbian UK [1]. It was broadcast in the USA as Power Lesbians on LOGO which profiled successful lesbians in Los Angeles. The two shared a relationship for a period afterwards.

In 2007, she is currently dating `Celebrity Treasure Island` host and former New Zealand rugby league player Matthew Ridge [5].
