With pregnancy rumors in the air, Ashlee Simpson hit an N.Y.C. party in a 3.1 Phillip Lim dress with an open back. Simpson told MTV, "When people deny [pregnancy reports]] it's probably because it's something they want to keep personal." Days later, Simpson released her second album, Bittersweet World
and a clothing collection
for Wet Seal.
