One look at the super romantic setting of the reception, and it's obvious the couple spared no expense.

... And there was even a fireworks show!

The wedding singer was none other than Sara Bareilles, who sang her romantic tune "I Choose You" -- the bride's favorite.

"I cried uncontrollably, it was so incredibly touching!" Casey wrote about the performance. "You made it so special singing my favorite song!!"

Casey, who donned a gorgeous white lace wedding gown, called her big day the "most incredible" night of her life.

Casey and Sean got engaged last August, and the Casey's Cupcakes entrepreneur gave ET the details on Sean's romantic proposal.

"Earlier in the day, he arranged to see my parents and my brother to get their blessing," the reality star recalled. "I was getting ready to go out to dinner with Sean and when I turned around to walk out of my dressing room, he was on one knee and simply said, 'Spend the rest of your life with me.' I screamed 'YES!', he put the ring on my finger and I cried tears of joy and completely ruined my makeup. It was such an amazing experience, so perfect and intimate!"

"Sean designed the ring with our family jeweler," Casey continued. "It is a pear-shaped 12 carat [ring] adorned with an additional 3 carats around the center diamond. It is absolutely stunning, he did such an exceptional job!! I couldn’t have dreamed of a more beautiful ring."
