Sad news, Beliebers: 6-year-old Avalanna Routh (a.k.a. “Mrs. Bieber”) has passed away.

The young girl, who suffered from a rare form of brain cancer, met her teen idol this past February, and their two hours of fun and games culminated in a pretend wedding.

Unfortunately, Avalanna lost her battle with The Big C this morning.

Justin tweeted the news to his fans: “just got the worst news ever. one of the greatest spirits i have ever known is gone. please pray for her family and for her. RIP Avalanna. i love you,” he wrote. “please show respect to her and her family. say a prayer for her and for them. i miss her.”

Our thoughts go out to Avalanna’s family, friends, and faux husband.
