R&B star Rihanna has hired President Barack Obama's ex-secret service staff to protect her after being hit with death threats.
The 25-year-old 'Diamonds' singer has increased security after a series of vile taunts following her first public appearance with beau Chris Brown at the Grammy Awards earlier this month, reported Daily Star.
One of the precautions being taken is to bring in two of �President Obama's ex-secret service agents to protect her.
"They have been on rotation 24/7 � standing outside her hotel room and on close call at all times. Nothing is being left to chance," a source said.
Angry fans turned on her after she rekindled her on-off relationship with the rapper, who beat her black and blue in 2009.
The pair were �spotted all over each other last week during a break in Hawaii to celebrate Rihanna's 25th birthday.
The Bajan beauty also has had her home fitted with a new security system, including a fully-equipped panic room.
Rihanna decided to beef up her �protection in the week a man was arrested for trying to break into her Pacific Palisades pad in LA.
But the intruder picked the wrong house and attempted to get into a neighbour's property.
