Maids of honor sing Justin Bieber parody toast

When these two maids of honor finished their speech and raised a glass, everyone thought they were done. Then... this happened. And everybody went nuts! A few pieces of relevant background info to understand the song better: These newlyweds dated for 11 years, starting when the bride was 15 years old. Her brother, Bryce, hated the idea because they were (and still are) best friends. And "Layla" is their dog!
