The new judges, plus presenters, all descended on the O2 Arena in London earlier today to meet fans, have their photos taken and then sit through a grilling from the press - who were then treated to a sneak preview of Saturday's show.

- Tulisa Contostavlos at the launch press conference<p> The singer used the official <em>X Factor</em> launch press conference as the platform on which to showcase her new blonde-streaked hair. We're not 100% convinced...</p>
- Kelly Rowland at the launch press conference<p> Kelly Rowland also opted for a fitted LBD for the launch conference, but her Versace number had some added injection of colour courtesy of bright green piping.</p>
- Kelly Rowland at the launch press conference<p> The former Destiny's Child teamed her low-back dress with killer wedges.</p>
- Gary Barlow at the launch press conference<p> New head judge Gary Barlow was looking decidedly dapper at the press conference. And quite rightly so.</p>
- Louis Walsh at the launch press conference<p> And then there was good old Louis, just looking like good old Louis.</p>
- The new judges at the launch press conference<p> And here they are, the new fab four. Now is it us, or does Louis look like he's missing his old mates?</p>
- Dermot O'Leery at the launch press conference<p> Ah we'd forgotten just how much we love Dermot! We think we're more excited about getting our weekly O'Leery fix back than we are about anything else <em>X Factor</em> related...</p>
- Caroline Flack at the launch press conference<p> New <em>Xtra Factor</em> presenter Caroline Flack showed off her pins in a micro mini LBD (something of a trend on this red carpet) teamed with leopard print booties.</p>
- Olly Murs at the launch press conference<p> Caroline's soon-to-be ITV2 side-kick, Olly Murs was also in attendance.</p>

- Kelly Rowland in Manchester<p> Kelly Rowland showed off her teeny-tiny waist in a white belted prom dress, teamed with fierce red ankle boots.</p>
- Tulisa Contostavlos in Manchester<p> In what we think is Tulisa's most stylish <em>X Factor</em> moment so far, the judge hit Manchester in a sweet pastel-printed dress and bow belt, teamed with matching bow-festooned heels.</p>
- Tulisa Contostavlos in Birmingham<p> Tulisa seemed to be channeling her inner Cheryl Cole for the Scotland auditions in a patterned minidress, teamed with glossy long locks and peep-toe booties.</p>
- Kelly Rowland in Scotland<p> Kelly Rowland got into the Scottish spirit, attempting the Highland Fling in her ladylike ensemble of printed skirt, pussybow blouse and uber-tall nude heels.</p>
- Tulisa Contostavlos in Birmingham<p> For her big<em> X Factor</em> debut, Tulisa stepped out in a dotty DKNY jumpsuit and chunky scarlet platforms.</p>
- Kelly Rowland in Birmingham<p> For her first official <em>X Factor </em>appearance, Kelly went all out in cropped Twenty8Twelve lace top, with black skirt and Louboutin heels.</p>
- Gary Barlow in Birmingham<p> Replacing Simon Cowell as the esteemed head of the judging panel, new boy Gary Barlow was looking decidedly dapper for the first round of auditions.</p>
- Louis Walsh<p> Finally a familiar face! With the appearance of the ever-present Louis Walsh, it suddenly feels like the <em>X Factor</em> again.</p>
- Dermot O'Leary in Birmingham<p> Also returning to the X Factor for another year, is the delectable Dermot O'Leary. Hurrah!</p>
- Olly Murs and Caroline Flack in Birmingham<p> Taking over from Konnie Huq, presenter Caroline Flack will be fronting ITV2's <em>Xtra Factor</em> - alongside alumni Olly Murs. The pair were colour co-ordinating in blues in Birmingham.</p>
- Tulisa Contostavlos at the launch press conference<p> Tulisa struck a pose in a demure (ish) Little Black Dress by Vivienne Westwood, teamed with towering stiletto heels.</p>
We know, we know, we keep moaning about how much we're going to miss Dannii and Cheryl (and sort of Simon) but we can't help but be just a teeny tiny little bit curious. Aren't you?
