Brad Pitt and Angelina Jolie confirmed their engagement just one month ago, and already they're walking down the aisle…sort of.

In a series of new spoof photos, artist Alison Jackson -- who famously recreated the royal wedding with lookalikes -- enlists two actors to stand in for Pitt, 48, and Jolie, 36, in full wedding attire.

While fans continue to speculate as to what Jolie's gown will look like, Jackson put her stand-in actress in a floor-length white gown with sheer sleeves. A shaggy-haired "Pitt" dons sunglasses and a gray suit and tie for the photo op.

Confirming their engagement April 13, the couple of seven years made sure their six kids -- Maddox, 10, Pax, 8, Zahara, 7, Shiloh, 5, and twins Vivienne and Knox, 3 -- were present when they made a pact to say "I do."

"Angelina cried and smiled" when Moneyball's Pitt gave her the tablet-shaped diamond ring he designed, a family pal tells Us Weekly. "Everyone hugged once she put [the ring] on. She went around and showed it to each of the kids."
