Singer Rihanna's superstar status apparently soured her relationship with Drake.

The duo recently split after a brief romance and according to sources, the rapper was jealous of Rihanna's superstar status and was keen to catch up with her, reports showbizspy.com.

`Rihanna has made her career and her name and Drake's just trying to do the same thing," said a source.

`He has goals and ambition and that's first and foremost in his mind. If Rihanna can't understand that then maybe it wasn't meant to be. He does still love her.

`She's being stubborn. When he told her she's too needy, she was like- 'All right, I'll show you needy,' and she's been doing her own thing since then, trying to make him miss her," added the source.
