The Saturdays have signed a development deal with E! to star in a reality TV show.

The five-piece British girl group - which consists of Una Healy, Mollie King, Frankie Sandford, Vanessa White and Rochelle Wiseman - have agreed terms with the network to have their personal and professional lives documented on camera.

According to the New York Post newspaper, the series will chart the band's move to Los Angeles and attempt to crack the US pop charts as well as show behind-the-scenes details of their concerts and studio sessions.

But it is the girls' private lives which will be of most interest to viewers with Mollie recently being romantically linked to Prince Harry.

The 24-year-old blonde beauty - who split from model David Gandy just a few months ago - first met the 27-year-old British royal at a polo match in 2010 and in recent weeks the pair have been partying together at Public nightclub and karaoke bar Bunga Bunga in London.

In March, Una gave birth to her daughter Aoife - her first child with England rugby player Ben Foden - and the pair are set to marry in the summer.

Rochelle got engaged to JLS singer Marvin Humes over the festive period and the couple are busy planning their nuptials.

It will not be the first reality TV show the band has starred in.

In 2010, they appeared in 'The Saturdays: 24/7' for British channel ITV2, which was six episodes and followed the girls on tour and preparing for the release of their single 'Missing You'.
