Jessica Alba split with CASH WARREN because he was terrified of commitment, according to the pair's pals. The actress reportedly ended her two-year relationship with the production assistant last week (begs22Jul07), after months denying the romance was on the rocks. Now friends reveal the break-up was relatively amicable, but prompted by differences in the couple's long-term aspirations. One tells the New York Daily News, "He (Cash) wasn't ready for marriage, and Jessica is. "It's simple as that. It's kind of cold that the press is saying she was just finished with him, because it isn't like that." And pals cite close friend Eva Longoria's recent French nuptials as the event that finally pushed her: "Seeing Eva get married made Jessica wistful. That was the reason Jessica seemed to be in a terrible mood in Paris."
