For the first time the royal couple visited the Abbey together, the place where they'll be married at the end of April.
The reason for the visit was to check out the full orchestra and boy's choir to hear a few selections of music, so they could choose what to include and what not to for their big day!
Here's what happened:
William, 28, and his bride-to-be, 29, alongside the groom's father, Prince Charles, arrived in a dark blue Jaguar around 8 p.m. Once inside, the trio sat in a pew a few rows from the altar while a full orchestra and a boy's choir rehearsed.
They "listened to some of the music that will be played at the wedding, but not all of it," a senior royal source tells Britain's Express newspaper. "The orchestra also had a few pieces that they had wanted the bride and groom to hear."
Sounds like a cute evening!
We bet they're getting so excited for the big day next month! All this planning is probably a little overwhelming, but we're sure they have people to help handle it all!
Prince William and Kate, we hope everything is lovely for you guys! We'd love to come!
