Jennifer Aniston is in London to promote her new comedy Horrible Bosses (have you seen it? I thought it was hilarious) but put a sexy spin on her standard LBD and chose a mini made of leather. Jen really surprised her fans at the actual premiere, showing up on the red carpet in a fresh and feminine Valentino Haute Couture dress straight off the runway. We don’t normally see her in embroidered, light colors! Which Jennifer Aniston look to you like better? Naughty or nice?
