Protective parent is accompanying the star on the job.
Rihanna's mother has stepped in to stop her from partying too hard.
The 24-year-old 'Where Have You Been?' singer is apparently experiencing an intervention from her parent soon after being hospitalized for exhaustion.
The singer - whose real name is Robyn Fenty - now has her Monica Fenty following her almost everywhere she goes in an attempt to make sure her child is well looked after.
A source told The Sun: ''Monica's moving in to keep an eye on her.
''Rihanna's dad, Ronald, was a crack addict. Monica's refusing to let her go down that path.''
Rihanna was rushed to hospital suffering with ''exhaustion and dehydration'' recently.
She tweeted a picture of herself attached to a drip in a hospital after reportedly spending the night partying at the Met Gala in New York, MediaTakeOut.com reported.
However, after a brief stay in the undisclosed medical centre, she was discharged and allowed to fly back to her home in Los Angeles.
One reason why she may be suffering with exhaustion is her extensive workout regime, with her trainer Harley Pasternake claiming she will even hit the gym in the middle of the night if necessary.
He said: ''Rihanna looks amazing right now. I've put her on a special 25-minute-a-day workout that consists of five mini-workouts. She does it five days a week, wherever she is in the world.''
