Tulisa Contostavlos looked like a shadow of her former self - in a positive way - as she stepped out in London last night rocking a brand new sophisticated look.

The 'Live It Up' singer certainly looked younger than her 24 years, baring a face stripped of the usual caked on make-up, giving her a fresh glow which was complimented well by a 50s style black shift dress.

Perhaps Tulisa's conservative look was down to the singer partying at the exclusive Mayfair members' club, The Arts Club, where she was dined with her fellow X Factor judges, Louis Walsh, Nicole Scherzinger, Gary Barlow and host Dermot O'Leary.

The singer's new look comes just days after Louis revealed he hated her blonde hair, which she recently dyed back to her natural brown locks. Tulisa explained the shocking peroxide hue by saying she was bored and felt like a change.

Well, Tulisa, we think your latest change is one you should stick with! Doesn't she look amazing?! Check out the pics below...
