Yes, it's the yellow bridesmaid dress that keeps on giving.

A pack of coiffed bridesmaid extras donned the same yellow dress we've seen Diaz wear over the past few weeks.

In the film, Diaz will reportedly stand-in for their late father and walk Grace's character down the aisle.

"Knight & Day" follows Cruise as a secret agent who pops in and out of the life of a single woman played by Diaz. The two race across the globe while Peter Sarsgaard's federal agent character pursues the fugitive couple.

Paul Dano, known as the brooding brother in "Little Miss Sunshine" and star of Spike Jonze's upcoming "Where the Wild Things Are," is set to play an "eccentric genius behind a revolutionary technology" in the flick.
