It turns out, that there's a very good reason why Louis did this. Apparently, he came up with this idea to surprise his wife Estelle with well wishes from some of the famous people they both look up to. "I try my best to come up with things that my wife will appreciate in life. I try to do one special thing for her every day. Sometimes just buying a chocolate. Other times planning takes a bit more time. So for our wedding day, I wanted to make sure there are a lot of little surprises for her throughout the day. This was one of them," he told.
