According to Cinemablend, who head it - apparently - from People.com, there's a curious twist to Spears' hospitalisation:
However, a 'reliable source' tells website People.com that, despite reports, Spears was not under the influence of any substance when she arrived at the hospital.
Of course, it could all be made up - Britney not on drugs being a more eye-catching headline than the reverse. But it's still all weird.
