Justin Bieber‘s “Believe” tour kickoff on Saturday didn’t just mark a new beginning, but also a tragic end.

The singer paid tribute to Avalanna Routh, the 6-year-old superfan who lost her battle with a rare form of brain cancer last week.

Bieber — who was also sick and vomited during the concert — dedicated his hit “One Less Lonely Girl” to Routh, whom he long ago nicknamed “Mrs. Bieber.”

As he performed, photos of her played on giant screens.

After the concert, Bieber wrote on Twitter, “Goodnight Avalanna. Tonight was for u. I love u.”
