Daily Mail Online can exclusively reveal the superstar singer has been embroiled in a heartbreaking bid to save Ronald Fenty from his drinking demons for the past year - even putting him through an expensive Malibu rehab program.

But all her hard work went up in smoke last Thursday as her star-studded charity party was reduced to farce before she even arrived.

In an exclusive chat with Ronald at his Beverly Hills hotel before he jetted out of Los Angeles, the 61-year-old spoke candidly about their spectacular bust-up, revealing how:

Rihanna put him through a $58,000 Malibu rehab program last year to save him from jail after he was arrested during a previous visit to California

• She flies him to LA every three months for urine tests and has the mini-bar emptied before he arrives

• She has frozen out Chris Brown and ignored him at their last meeting

• He dislikes Rihanna’s best pal and constant companion Melissa Forde

• She is still single and unable to find a man

• She is NOT pregnant, despite widespread claims by magazines and websites
