Rihanna and mother

Rihanna was so depressed and brokenhearted over her latest failure at Love that her mother jetted to her side to talk her down off the ledge, according to my confidential source.

“Rihanna was suicidal. She considers herself a complete failure,” said my source. Rihanna’s people considered canceling her LA concert, until her mother flew to her side and gave her the only true Love she has ever known.

Rihanna, 25, admitted she doesn’t understand love during her concert at the Staples Center on Monday.

“How many of you are in love? How many of you hate love? How many of you don’t f––ing understand it? I’m in that group,” Rihanna said on stage, before launching into her song “What Now,” off her latest album.

Rihanna and Chris Brown recently broke up after reuniting several times since their 2009 domestic incident that resulted in his arrest.
