Britney Spears was seen wrapped in a blanket and in apparent distress as she left Los Angeles' Chateau Marmont, where an ambulance was called Wednesday night. A source tells ET, 'Britney is now home safe and is fine.' It's unclear if paramedics were called on account of the pop star. 'Britney came out with Paul Richard Soliz and some others,' an eyewitness explains to ET. 'Someone gave her a blanket to throw over and she had a pillow covering her front. She took a few steps and turned around and went back, not getting into the stretcher they had brought out.'
