What do Nicole Richie and Joel Madden have in common with newlyweds Jason Biggs and Jenny Mollen? Apparently, a love for sushi. The two couples joined Chef Nozawa and others to attend the SugarFish by Sushi Nozawa grand opening party in Marina Del Rey last night. Baby Harlow stayed home for the night while her parents partied, but that's OK; we doubt she's old enough to enjoy yummy sushi anyways.
