Cameron Diaz has slammed recent reports that she and boyfriend Justin Timberlake have purchased a $25 million beachfront estate in Hawaii. "I wouldn't buy anything for less than $35 million!" Diaz joked to Self mag. "No! Who has $25 million to spend on a vacation house? That's insanity!" Diaz insists that while she loves to surf in Hawaii, she stays in a hotel or rents a house when she's there.source
