Justin Timberlake and Jessica Biel dress in matching outfits at Runner Runner premiere

It's often said that husbands and wives morph into each other after years together.
And recently married Jessica Biel, 31, and Justin Timberlake, 32, seem to be doing just that.
Appearing together at the premiere for Justin's new movie Runner Runner in Las Vegas on Wednesday, the couple wore matching tuxedo jackets, white shirts and fitted trousers.

Jessica, who has recently changed her name from Biel to Timberlake after marrying Justin in October 2012, looked sleek and sophisticated in a double breasted black tuxedo jacket.
The couple both wore white shirts buttoned up to the neck, fitted trousers and black shoes.
Biel wore little make-up and in doing so highlighted the fact her colouring is very similar to that of her husband.

Joining the pair on the red carpet at the Planet Hollywood Casino & Resort were fellow Runner Runner stars Ben Affleck, Gemma Arterton and Anthony Mackie.

Affleck, who laughed and joked with Justin on the carpet, kept his look understated in a pale grey suit and matching skinny tie.
And Grey's Anatomy actor Anthony Mackie, 34, was possibly the best dressed man at the event, in a silver-grey jacket, navy slacks, blue shirt and striped tie - but ruined the look by chewing a wooden toothpick  as he posed for pictures.
