Prince George and Princess Charlotte have had a summer schedule packed full of weddings, where they have participated as page boy and bridesmaid. But by now, the novelty of the roles has waned, and it appears as if the royal siblings are ready to just be kids again.

Case in point: Their less than excited facial expressions in one of Princess Eugenie's official wedding portraits, which were released by the palace on Saturday.

In the candid snap, photographer Alex Bramall captured George and Charlotte mustering up the energy to grin for the camera alongside the bride and groom, but they weren't their usual smiley selves. Perhaps, it was past their nap time?

However, in another shot, they pulled it together, with George practically beaming and Charlotte practicing her best Duchess slant.

Another photo showcases a romantic moment between Eugenie and husband Jack Brooksbank while riding in a horse-drawn carriage.

And finally, the bride's second wedding dress is revealed in a fourth picture at the evening reception, which was held at Royal Lodge in Windsor. Eugenie changed into a Zac Posen pleated blush gown, while Jack suited up in a tailored tux.
