I read somewhere that there was a post from her personal assistant on Britney's site somewhere to the effect that everyone around her (Britney) was deeply concerned about her actions and behaviors in recent days and they were doing everything possible to help her get back on the right track.

Also, supposedly Britney flew to Antigua to check into Crossroads, a rehab facility founded by Eric Clapton, but left after a day. This was denied by her publicist, but confirmed by someone at her record company, so maybe there's a bigger problem here.
