He also said that he had spoken to Ghalib about Spears' mental state."She was just so overwhelmed. She was panicked. She was so nervous," Hasan explained during an interview on The Early Show. "She was really, really stressed out in a major way. She knew from the moment that she left home, there were [news] helicopters following her. "I mean, normally, on a day-to-day basis, OK, it's kind of like her friends are with her on a daily basis, kind of following her, but this was just really panicking.""When she got to the courthouse, you know, even Adnan was telling me that it was just way beyond her, and she was nervous," he added. "She was panicking. And all she was saying is, 'I need to pray. I'm praying. I'm praying. I'm praying.'"Spears has been banned from seeing her two sons until the next hearing takes place on February 19.
