The Saturdays are flying out to Los Angeles to film their new reality TV show.

The British girl band - made up of Rochelle Humes, Una Healy, Mollie King, Frankie Sandford and Vanessa White - have signed a development deal with E! to shoot the fly-on-the-wall programme which will follow them in their bid to make it In America.

All the girls have left the UK for a few weeks to spend time in Hollywood, with cameras there to capture their every move.

Una - who has a four-month-old daughter, Aoife Belle, with husband Ben Foden - tweeted yesterday (07.08.12): ''Flying to L.A tomorrow for a few weeks and need to start packing!!Got help from Mrs. Mammy Healy for Aoife Belle:) nervous and excited will be v sad saying goodbye to my hubby @ben_foden :( (sic)''

Rochelle - who married JLS star Marvin Humes last month - added: ''Hardest goodbye I've ever had to do.''

And it seems her new husband will miss her lots as he took to JLS' twitter account to wish all the girls luck.

He wrote: ''wishing @RochelleTheSats and all @TheSaturdays all the best in the US!! Go and smash it girls! Marv x (sic)''

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 ran for six episodes and followed the girls on tour and preparing for the release of their single 'Missing You'.
