Jessica Alba and boyfriend Cash Warren (not pictured) arrived in style at the Saint Germain l'Auxerrois church in Paris for the lavish Catholic ceremony. Like all other guests, the couple surrendered their cell phones before entering the historic site, which was filled with white lilies for the occasion. Also in the pews were longtime Longoria pals Sheryl Crow, Mario Lopez and American Idol emcee Ryan Seacrest.
