I'm bringing the Sex Factor! Leggy Britney Spears upstages Demi Lovato with TWO short dresses at unveiling of new look panel

Britney Spears is proving to be quite the femme fatale before the second season of X Factor USA has even started.
The squabbles between the judges and their categories are yet to commence, but the Toxic star is showing rival castmate Devi Lovato that when it comes to the fashion stakes, she's a clear winner.
As the line-up for the second series of the reality show was unveiled today, it seems the mother-of-two couldn't decided which dress to wear, so opted for two to maximise column inches.

During today's photocall in New York, Britney posed in a figure-hugging strapped white dress with Demi, Simon Cowell and LA Reid for an intimate snap which she tweeted online.

Demi, on the other hand, was seen wearing the same dress on two separate Kodak moments. However, credit where it's due, she was a little more experimental in her spiderweb pattern gown.
Today, Hollywood's worst kept secret was finally confirmed.
Britney, 30, has officially joined the judging panel along with Disney star Demi, 19.

Simon could barely hide his delight, tweeting: 'Can't believe it's finally happened. Very exciting!'
While no details as to how much Demi's contract is worth have been leaked, Britney is thought to have negotiated a $15 million pay packet to be a panellist on the show.
Britney and Demi will replace Paula Abdul and Nicole Scherzinger - who were axed after poor ratings on last year's debut series - sitting alongside show boss Simon and music executive L.A.
