There are plenty of things that can make a wedding special, from gorgeous fall vibes to a little unexpected rain. But for two brides who recently said 鈥淚 do,鈥 the special something was much bigger: Sam Smith surprised them with a personal performance.

When Bec Baran and Lisa Best鈥檚 wedding day rolled around, it was revealed that Best鈥檚 niece and best woman, Katie (who is apparently an AMAZING secret-keeper), had arranged for someone to sing for them at their reception. And while we鈥檙e sure that the women would have been touched by any thoughtful tribute, Katie had something pretty epic in store.

鈥淪o, Lisa and Bec, it is time for the surprise of your married lives. With a little bit of help from Lisa鈥檚 best woman, we have been keeping a big secret from you,鈥 the DJ announced, as seen in a clip from the occasion in the 鈥淪tay With Me鈥 singer鈥檚 BBC special. The newlyweds were visibly shocked when the music spinner added, 鈥淧lease welcome Sam Smith!鈥

After performing his heartwarming tune 鈥淟atch,鈥 he then congratulated the brides, saying, 鈥淚 saw the ceremony in London and it moves my heart so much to see you guys do this today. I truly hope you have a wonderful, wonderful life together. Thank you for having me here.鈥

Best was blown away: 鈥淲hen he walked through the door, I just thought, 鈥榃ow, that is actually Sam Smith!鈥 This does not happen to us. All of my friends and Bec鈥檚 friends and family were really shocked. It was just another level.鈥

鈥淛ust being a part of someone鈥檚 day like that means the world to me,鈥 Smith said of the special moment, adding, 鈥淭hey鈥檙e so in love. It鈥檚 just incredible. They鈥檙e so in love and it鈥檚 so beautiful.鈥
