According to a stunning new report in OK magazine, Kevin Federline was at the pop star’s Malibu mansion on Friday when she arrived home from rehab, and a blowout between the exes broke out.
“They had a huge argument,” revealed OK’s Rob Shuter. “Kevin threatened Britney that he was going to have people test her hair to find out exactly what she’s been up to. She was so scared. That was what made her have her head shaved.”
