The `Stay` hitmaker is said to be pining for the "love of her life" Chris Brown following their recent split and his decision to rekindle his relationship with fashion designer Karreuche Tran, and is thinking of checking into a clinic for a heartbreak therapy course to get over him for good.
The 25-year-old pop star is likely to begin the 12-step programme - which follows the same format as alcohol and drug rehabilitation - during her upcoming six-week break from her `Diamonds World Tour` at The Ranch clinic in Tennessee.
A source told the new UK issue of Grazia magazine: "Rihanna is still desperately in love with Chris. It`s like she`s obsessed with him and, although he`s told her it`s over, she just can`t get over him.
"After talking it through with a psychotherapist, Rihanna is now considering doing a 12-step programme to get rid of her demons."
The Ranch`s `Women`s Love and Sex Addiction Treatment Programme` helps women with issues with "attracting troubled, addicted, abusive or otherwise emotionally unavailable partners" using treatments as varied as counselling and equine therapy.
Rihanna and Chris, 24, dated for three years, but split in February 2009 when he assaulted her after a pre-Grammy`s party. Following a two-year romance with Karrueche, Chris and Rihanna announced they were officially a couple again January 2013 after months of speculation and confused Chris claimed he was in love with "two women" but their turbulent romance has now ended again.
