X17 has learned that Gwen Stefani has just presented herself at Cedars-Sinai! Our photographers saw Gwen's black Range Rover pull up to the hospital as part of a three-car convoy full of Gwen's family members; the pregnant pop star hopped out and was quickly whisked inside by waiting police officers.

Isn't this exciting? Just think - pretty soon, Sean and Jayden might have another little playmate!

We'll bring you more on this story as we hear it - stay tuned!
