The end may be near for Cameron Diaz and Justin Timberlake

It might sound crazy, but it ain’t no lie: insiders say Justin Timberlake may be ready to say “Bye, Bye, Bye� to girlfriend, Cameron Diaz. Diaz and Timberlake have been together for nearly three years, but she may be pushing for an even longer commitment. At 33, free-spirited Cameron may finally be longing for marriage and a family. 25-year-old Justin, on the other hand, still has the need to sow his oats.

A source for the New York Daily News said, "Justin has told friends he's 'confused.’ He likes Cameron a lot. But he's 25. He says he just doesn't know how committed he can be. He needs space. Cameron is a little controlling."

Still, Justin owes a lot to Cameron - at least one paycheck, anyway. Rumor has it, the actress landed Timberlake his role in the upcoming film, Shrek 3. The couple will be catering to that film’s potential audience next month when they attend the Nickelodeon Kids’ Choice Awards, hosted by Jack Black. The 2003 awards were the place were Cameron and Justin first started their romance.
