Britney not okay for OK! Interview

OK! Magazine's editors have chosen not to sanitise a "heartbreaking" interview with Britney Spears, during which the pop star reportedly mopped up dog mess with a Chanel dress and expressed fears her ceiling was about to collapse.

Editor-in-chief Sarah Ivens insists the interview, which will appear in the upcoming issue of OK! Will leave readers "shocked and sad".

Insiders tell TMZ.com Spears had a "total meltdown" during the interview and accompanying photoshoot, refusing professional make-up and hair help and insisting her untrained friends style her.

Sources tell the website Spears was "completely out of it" and "erratic" during the shoot, and took "frequent bathroom breaks".

TMZ.com reports: "She was also completely paranoid during the entire interview, fearing at one point the ceiling was about to cave in on her."
