Nicole Richie has checked into Cedars-Sinai Medical Center in Los Angeles. The reality TV star is nine months pregnant with her and boyfriend Joel Madden’s first baby. Dad Lionel Richie and mom Brenda have already arrived at the hospital.

“Lionel is there with his youngest daughter and several other unidentified people,” says an on-site spy.

“She’s going to start pushing soon,” Joel Madden was overheard saying.

Fellow mom-to-be Christina Aguilera is also at Cedars preparing to give birth, according to published reports.
