Jessica Alba's on/off romance with CASH WARREN appears to be back on, after the couple were photographed snuggling on a California beach. The Fantastic Four beauty, 26, and director's assistant, 28, were alleged to have split last month (Jul07) after two years together. Friends claimed they split because Alba wanted to marry, while Warren was reluctant to commit. However, the pair were spotted strolling arm-in-arm at Pacific Palisades on Thursday morning (23Aug07).
