 'Alexander McQueen: Savage Beauty' 

exhibition at Victoria & Albert Museum in London, England. 

 Diana was wearing a gorgeous black short-sleeved plunging

neckline gown with a blue bow detail by Johanna Ortiz.

And yup, there was a wardrobe malfunction that happened 

there and from the looks of it Dianna was not

 even aware of the nip slip happening. 

She's also wearing two fabulous multi-colored 

Annina Vogel necklaces.

Actress Dianna Agron looks so classy and lovely wearing her Vivienne Westwood dress and a red pair of Brian Atwood shoes at the premiere of her new film 'I am Number Four'. She's also carrying a VBH bag and accessorized with jewels by Fred Leighton. Her hair was a simple but elegant chignon. The star of the film and Dianna's current squeeze Alex Pettyfer was there too and is dressed in a 3-piece pinstripe suit by Polo Ralph Lauren. They make a lovely couple.
