OMG, this explains everything about A-Rod's relationship with Cameron Diaz. US Weekly claims she and Kate Hudson are "locked in a bitter battle over Alex Rodriguez... An insider believes Diaz is bedding Rodriguez as a form of retaliation after Hudson hooked up with Justin Timberlake in January 2007 -- just two days after the couple of four years split." The insider says, "Kate thinks it's payback, pure and simple," while Diaz's friend offers, "Cameron was actually in a serious long-term relationship with Justin. She thinks it's a joke Kate would be mad. Kate is only upset because she hates being single." Another claim: Hudson got breast implants after they broke up because A-Rod likes "busty women."
