Nicole Ritchie checks into hospital!

Nicole Richie, who is expecting her second baby with boyfriend Joel Madden, reportedly checked into a Los Angeles medical center at the end of last week.
Website X17 reports: “The day after DJ AM's memorial, rumors began to fly that Nicole Richie - Adam Goldstein's former fiancé - was admitted to a local Los Angeles hospital.
Nicole's due date was believed to be early September, so all signs point to baby no.2 being born.
Joel recently confessed that him and Nicole can’t wait to welcome their second child into the world, but they're staying mum on the sex of the baby.
