Nicole Bumps Xtina: Race Is On!

Earlier today we told you Christina Aguilera was at Cedars and would soon be delivering her bundle of joy.

Well, move aside, Xtina—the birthing team is needed in Nicole Richie's room, stat!

The Simple Life star is also at Cedars, and according to Usmagazine.com, she's already in labor!

"She's going to start pushing soon," baby daddy Joel Madden was overheard saying. He's at the hospital with bro Benji.

Nicole arrived at the L.A. hospital Thursday night via a secret entrance, the magazine is reporting.

Best of luck to both ladies—no matter who comes in first!
