Star Styles at the London Valentine's Day Premiere

Jessica Alba, Ashton Kutcher, Topher Grace, and Emma Roberts were at the European premiere of Valentine's Day which was held in London on February 11.

Jessica rocked a blue and green check Prada frock plus kicking blue Miu Miu lace-up ankle boots. She also wore jewelry from Lanvin.

Demi Moore, who was supporting husband Ashton at the premiere, went for a black, white flower adorned, Marchesa dress plus simple Roger Vivier clutch and Ferragamo pumps.

Emma kept it quite simple in a little black Kova & T dress and nude Brian Atwood pumps but added glitz with a vintage necklace and her gorgeously sparkling Swarovski bag.

Emma's Kova & T dress is available at shoplesnouvelles.com, costing $200.00.
