When Louisa met Rob, she knew there was something familiar about him — once they started talking, she realized that he had been on a poster hanging in her room [1] as a 12-year-old girl! He was in a German boy band that Louisa had liked. Fast forward to today, and the couple who met by chance in Los Angeles are more in love [2] than ever.

Louisa worked with Dove and its Amazing Moments campaign to surprise Rob with a romantic proposal. "Amazing Moments shines a light on the fact that sometimes the moments that make us sweat are the most amazing moments of all," the company says. Watch the video to see how the proposal [3] went down, and prepare for some happy tears.
