Pixie Lott stuns in a pink satin dress as she cosies up to fiancé Oliver Cheshire at Lost in Space event

PIXIE Lott and fiancé Oliver Cheshire were the definition of couple goals as they attended the 60th anniversary of the OMEGA Speedmaster on Wednesday night.

The attractive pair put on a close display upon arrival at the Turbine Hall inside London's Tate Modern, with Oliver wrapping his arm around Pixie.

Sporting her newly-dyed pink hair, Pixie matched her locks with a satin dress and carried a silver clutch which matched her heels.

She finished her glamorous look with pink lipstick and dangly silver earrings, while Oliver was typically dapper in a navy three-piece suit and dark brown shoes.

The bash to celebrate the iconic wristwatch was attended by a star-studded crowd including the likes of Ellie Goulding, Gemma Arterton and Toby Huntington-Whiteley.

Singer Ellie looked great in an unusual LBD with sheer sections, while actress Joely Richardson caught the eue in in a stylish navy jump suit with a loose waist tie.

Wearing her blonde hair straightened to perfection in a side parting, she smouldered as she stared into the camera.

Dapper model Toby gave off a James Bond vibe in his black suit complete with bow tie. Wearing an almost identical outfit was Professor Brian Cox, who was his typically smiley self beside partner Gia Milinovich.

Boxer David Haye paraded his moon boot, which is helping his recovery from achilles surgery, while wearing a formal suit.

Classy as ever, Liv Tyler stunned in a pink frock with vivid red streaks in the skirt which matched her heels.

Amber Le Bon's gown incorporated earthy tones for an unusual finish, while Erin O'Connor couldn't be missed in a vibrant full length red dress.

Other stars of stage, screen and catwalks included Hollywood stars Jeremy Irvine and George Clooney who both looked dapper in tuxedos.

British babes Gemma Arterton and Laura Carmichael appeared to be in playful moods as they posed together at the bash.

And Joely Richardson offered extra elegance and sophistication as she rocked up in a sleeveless outfit.

Stars from around the world included half-Swedish, half-Thai beauty Praya Lundberg who turned heads on the red carpet in an arresting black dress with gold detail.

Liu Shishi - one of China's highest paid TV actresses - stunned in playful black dress with a painted-on bow effect.
