It's Almost Baby Day for Ashlee Simpson

Pop star Ashlee Simpson is hosting a last-minute baby shower party in Los Angeles on Saturday.

The singer, who according to husband Pete Wentz is "very pregnant", will send out invites to close friends and family members early on Saturday in a bid to keep the party and the location a secret, according to reports.

Meanwhile, anxious Wentz says, "I'm on call permanent right now... It could happen any day now."
