A rep for the model – who is expecting her third child – told Reveal she was admitted to hospital on Saturday evening (10 August) and kept in for observation for two nights.
On admittance she was given fluids through an IV after being unable to keep anything down. A diagnosis hasn't been made yet but most importantly for Danielle is the fact her unborn child's heart rate is OK.
Danielle had tweeted yesterday that she was "very sick at the moment", adding a few hours later: "Just come off drip after 24 hours now just on iv antibiotics 4 next 8 hours more & then hopefully get home to my hubby and babies tomorrow."
Doctors will reassess her this morning to see how she is.
The 29-year-old revealed back in February that she and footballer husband Jamie O'Hara are expecting their third child together.
They are already parents to sons Archie and Harry and Danielle has confirmed their third arrival will be another boy.
