Una and Rochelle came on the show to talk about their FIRST NUMBER ONE, and a few other bits and bobs too!
Don't tell anyone... But Una and Rochelle may be our favourite members of The Saturday's.
So it was lucky that they were the two who managed to squeeze us in to their busy "breaking America" schedule!
We chatted about the new single, the US, and Sean Paul.
Una even gave us her Sean Paul impression!
