Cameron Diaz is Tempermental, Jealous

Cameron Diaz, who recently split with Justin Timberlake, exploded on Jessica Biel, after discovering her on the rooftop with Justin. According to the National Ledger,

Diaz followed Timberlake to the In Style party at the Hilton Oasis, where “they had an awkward conversation.” The “Charlie’s Angels” star then trailed Timberlake to the Beverly Hilton rooftop for the Universal party, where she found him chatting up Biel - and screamed at the “Illusionist” star. “If that’s how she wants to get him back, it won’t work,” said our insider. “She’s desperate.”

Just what every man wants… to be followed by an ex-girlfriend after the relationship ends. Or, better yet, have an ex-girlfriend scream at a woman the man was just talking to. Great.
