Nicole Richie is in hospital. The 27-year-old star, who is expecting her second child with partner Joel Madden, reportedly checked into a Los Angeles medical center at the end of last week.
X17 reports: "The day after DJ AM's memorial, rumors began to fly that Nicole Richie - Adam Goldstein's former fiancee - was admitted to a local Los Angeles hospital. Could she finally be ready to give birth???"
Nicole's due date is believed to be early September.
Nicole - who already has 19-month-old daughter Harlow with Joel - attended the ceremony in remembrance of DJ AM on Thursday.
An onlooker said: "The crowd was very hip and eclectic. It was a very somber and sad crowd."
The service was structured like an Alcoholics Anonymous 12 steps meeting in tribute to the 36-year-old star, who had battled substance abuse.
Joel has previously revealed he and Nicole can't wait to welcome their second child into the world.
The Good Charlotte frontman said: "We're excited about it. It's going to be great."
Nicole's father, singer Lionel Richie, recently confessed he hopes the couple will have a son.
He said: "It's very exciting. Joel is hoping for a boy, but knowing Nicole she's hoping for a little girl again. They're not telling me what sex the baby is because I'll tell everyone!"
"Nicole is the mom of moms. She's in love with the whole concept."
