It's hardly surprising to see Jennifer Aniston looking amazing at the UK premiere of Marley & Me, because lets face it, this 40-year-old beauty just never gets it wrong!! 

Miss Aniston chose a floor length sky blue gown, accessorising her strapless shoulders with a variety of chunky necklaces. Thankfully her clever stylist made sure her dress fell from a fitted corset, making the most of Jen's amazing figure. 

What's more we love how the actress admitted she couldn't brave London's chill, by giving in and putting on a black jacket. No embarrassing shivers and strained posing here! Smart lady.

Sadly John Mayer and Kate Hudson didn't make an appearance. Boo!
