Adele

With respect to her career and relationship, Adele seemingly has it all: Millions of albums sold, a pile of Grammys, a boyfriend with whom she's expecting a child. But one thing she doesn't have in her life is a father.

Adele's dad split when she was just 3 years old, leaving her mother to raise her alone. Despite the fact that he's publicly expressed a desire to reconcile with her, she refuses to speak with him. In an interview, she even said that if she ever sees him, she'll spit in his face.
