Reports claim she's under surveillance after her rumoured meltdown...
Hard-working popstarRihanna has allegedly been put on 24-hour health watch, ahead of her headline stint at this weekend's Capital FM Jingle Bell Ball.
According to The Mirror, Mercury record label executives have requested that the Barbadian beauty be put on surveillance - after she reportedly had a backstage meltdown and almost cancelled a gig in Dublin last Friday, 25th November.
Her mentorBeyoncé is thought to have convinced RiRi to carry on with the show, with the S&M hitmaker later tweeting: "I'm so light-headed!"
A source told the newspaper: "She’s filming her Loud tour DVD in December and her team is determined that she looks, acts and performs at her best."
The insider added: "They are currently in talks with Mariah Carey’s trainer, Patricia Gay, to fly in and start training.”
