Britney and Justin dated from 1999 to March 2002, although Justin’s mother has said they were together for “10 or 11 years” in all. The breakup was brutal for all parties — and has become a central part of Britney’s legal defense against Lufti’s defamation claims, according to TMZ. In documents obtained by RadarOnline, Jamie Lynne Spears and Britney Spears' attorneys argue that Britney and Justin "had a big relationship, and it ended painfully," adding, "In 2003 her parents noticed that she had changed over the breakup of her and Justin and noticed she was depressed….[Britney] went to Vegas and got married to a childhood friend for 55 hours and they realized that she was becoming distant with her parents and become concerned she was using illegal substances."
In their opening arguments, Jamie Lynne and Britney’s team of attorneys argue the split from JT caused the once-cheery pop star to become “angered” — eventually leading to the series of 2007 incidents illuminating erratic behavior, culminating in a forced psychiatric hospitalization. Lufti’s team continues to allege the “meltdown” was caused by drugs, and that Lufti was just trying to be a “calming” figure in Britney’s otherwise chaotic life. Britney's attorneys, meanwhile, allege Lufti took advantage of Britney, according to the legal documents obtained by RadarOnline. "Britney was at her most vulnerable when she met Sam Lutfi...Over the next couple of months things just got worse. An acquaintance sent an email to Jamie telling Britney to get away from Sam Lutfi because he will make her kill herself."
