UK based girl group The Saturdays welcomed the next step in their successful career last night (January 15) with a live performance on America's iconic 'The Tonight Show with Jay Leno'.

The ladies treated the studio audience to a rendition of 'What About Us' and thanked the host via their official Twitter page for allowing them to be a part of his programme: "Mr @JayLeno! Thanx for having us on your show!"

Nicki Minaj was also a guest on the show and Saturdays' member Rochelle Humes tweeted a photograph of the girls excitedly posing with her on the set.

Following their appearance last night, The Saturdays performed on 'The Today Show' this morning (January 16) and sent a message via their social networking page to let fans know they enjoyed it: "Thank you to @todayshow for having us, we had a blast chatting & performing 'What About Us'."
