The X Factor live shows kicked off over the weekend which meant the start of this year's style showdown between Tulisa Contostavlos and Nicole Scherzinger.
On Saturday night, Tulisa paired her midnight blue gown with a matching statement necklace and peep-toe heels, while Nicole opted for a sheer LBD, with a missing sleeve.
On Sunday, the girls stepped things up a level in strapless mini dresses. Tulisa braved a bright pink number paired with matching lipstick and lace-up heels but Nicole went for gold in a metallic design and a glossy, berry pout. So who got their looks right on week one?
