Leggy lady Karlie Kloss dazzles in figure-hugging gown with thigh-split at Zoolander No.2 premiere in Madrid

She was recently named the face of Topshop's spring line, marking her second campaign for the fashion company.

But on Monday night model Karlie Kloss traded high street for high glam as she attended the Spanish premiere of Zoolander No. 2 at the Capitol Theatre in Madrid.

The 23-year-old beauty turned heads in a figure-hugging, sleeveless gown with deep thigh-split.

The back of the Carolina Herrera dress was largely open, except for two shiny, crisscrossed straps. 

The sky is the limit for this 6ft 1in glamazon as she added a few more inches with a pair of towering, strappy heels.

The former Victoria's Secret Angel opted for an all-black ensemble, but she added a spot of colour with burgundy toenail polish.

Karlie, L'Oreal Paris's latest spokesmodel, played a subtle make-up game, wearing a light pink lip, eyeliner and a touch of blush that gave her rosy cheeks and helped define her already enviable cheekbones.

She happily posed with photographer Mario Testino, who previously photographed her alongside Eddie Redmayne for a spread in Vogue magazine called 'Temptation Island'.

Currently an undergraduate at New York University, she leaned on Mario repeatedly and at times flung back her hair, all the while showing off her gorgeous, floor-sweeping gown. 

She was full of smiles, but also worked a fish gape - subtly opening her mouth to add a sultry, but not overly sexualised, flare to her poses.

Zoolander 2, the sequel to the wildly popular 2001 comedy, sees Ben Stiller reprise his role as top male supermodel Derek Zoolander, with Owen Wilson portraying his best friend and fellow model Hansel McDonald.

Penelope Cruz takes on Valentina Valencia, an Interpol special agent with a penchant for riding motorcyles.

At the premiere the 41-year-old actress looked radiant in a white and gold gown with trail, playfully working her way past photographers.

She and Ben, who also directed the film, worked the famous 'blue steel' pout, which he popularised in the first Zoolander.
