They're pretty well known in the UK, but relatively unknown in the US.  They're being compared to the Spice Girls, but mostly because there's five of them, and they're British.  They are "The Saturdays," and recently landed in the U.S.

They hope to follow in the footsteps of fellow UK-ers "One Direction" and gain the kind of fame the boys of 1D have had since making their way over.  The ladies are stalked by the paparazzi in England where every move is followed.  But here, everyone is wondering who in the world these five girls are, and why there is a camera following them.

The five, Una Healy, Mollie King, Frankie Sandford, Vanessa White and Rochelle Humes are filming for an upcoming reality show "All Fired Up."

On coming to the US, one of the girls, Mollie, told the UK's "Daily Mail,"

'I’ve just been worried about leaving my Mum and dog. But I’m so excited. Ever since we started, we’ve said we want ‘world domination’, and now it’s happening!'

Well, I don't know about "world domination," but they may have a starting point.  The Saturdays have just signed their first US record deal and hired producer Rodney Jerkins--who has masterminded hits for Michael Jackson, Britney Spears, Whitney Houston and Justin Bieber among others.

Their debut single here will be "What About Us" featuring Sean Paul.

Unfortunately, (or fortunately, I guess,) I don't think they'll ever be as big as the Spice Girls.
