LATEST: British actress Billie Piper insists she is "fit and well" after falling ill over the weekend (03-04MAR07), and is delighted with how her debut performance in West End play TREATS went last night (06MAR07). The Doctor Who star collapsed just moments before she was due to appear at London's Garrick Theatre and was taken to hospital where she was reportedly treated for recurring haemorrhaging cystitis. But the 24-year-old is thrilled with her first show last night (06MAR07) and is looking forward to the play's official opening on Thursday (08MAR07). She said, "I'm doing really well. It is going well and I am really pleased." Piper also thanked her ex-husband Chris Evans, who attended the preview, for his support, adding, "It was really good having Chris here - I could hear him laughing. Bless him for being supportive."
