Posted August 28, 200816 yr Writer: 'Britney is highly unstable' Thursday, August 28 2008, 20:33 BST By Alex Fletcher, Entertainment Reporter Rex Features Author Ian Halperin has claimed that Britney Spears is "highly unstable". Halperin, who is currently promoting his new book Stalking Britney: Britney Under Siege, said the singer is "sensitive" and "insecure". He told In Touch: "She's on a high right now, but her life goes in circles. "It's like a roller coaster ride. She's a person who is highly sensitive, and just one little thing could set her off. "There's no doubt, based on the last two years, that she is a highly unstable person." He continued: "At 15, she had a huge breakdown and had to return home to Louisiana. She was very insecure and felt like she wasn't pretty."
