According to Us Weekly, Sel had a total breakdown at Taylor Swift's recent 25th birthday party, and it was all because of her ex Justin Bieber. She totally started crying, embarrassed herself, and even put her famous "boyfriend" on blast.
"She shouted, 'No one understands me! My boyfriend doesn't even understand me," an insider told the mag. She left bystanders like Sam Smith, Jay Z and Beyonce with looks on their faces like "Wtf?"
This dramatic scene took place on the upper terrace of the building. The rest of the party was reportedly booming, and having a blast downstairs.
All of this comes after Selena just revealed during a radio interview that she's single. Since then, Justin has been spotted all around the world with model Hailey Baldwin. Could all of that have her stressing a bit?
