Happy Birthday, Jess!

With a little help from some very famous friends, Jessica Simpson celebrates the big 2-5 with a blowout bash

WHAT THEY GOT!

The b-day girl gets to the point with pal Gyllenhaal, who was among the guests with plenty to celebrate: Everyone got gift bags by Silver Spoon stuffed with goodies like Paul Frank backpacks, Wolfgang's Vault vintage music tees, Lush, Benefit and Rosie Jane cosmetics and workout gear from Hard Tail.
