They're both ladies of The X Factor, they both like to wear nice frocks, they've both got new singles to flog and they both rocked up at the BBC radio studios in London today.
Cheryl showed up first thing this morning to push her single Call My Name on Radio 1's The Chris Moyles Show, while Tulisa stopped by Radio 2 this afternoon to chat about her record Young.
No doubt after seeing Cheryl looking flipping uh-mazing as she rocked up in a pair of printed jeans, Tulisa put that little bit of extra thought into her outfit today.
But who looked best - the original X Factor style icon Cheryl, or the new kid on the block Tulisa?
There's only one way to find out... FASH OFF!
