Nickelback frontman Chad revealed he cried when he saw his bride – clad in a black Monique Lhuillier gown – at the altar.
"I had goosebumps from head to toe and my eyes filled with tears. It's a moment I will never forget as long as I live," he said.
His new wife added, "My body was overtaken by emotion. I saw him and he was so calm and happy. He had a tear coming down and he wiped it away. I felt so good walking to him. It made me feel like a complete woman."
Explaining the wedding's dark, gothic theme, Avril told HELLO!: "I wanted it to be over the top. I'm obsessed with castles and I love French décor and Goth. I found this castle and it was perfect. I also wanted to make sure it was a crazy vacation and an experience of a lifetime for our guests.
