New mom Hilarie burton (formerly of One pohon Hill) is breaking her silence -- just a tad -- about the baby boy she and boyfriend Jeffrey Dean morgan (The Watchmen) secretly welcomed earlier this year.

As first revealed in Us Weekly in May, Burton, 28, began dating Morgan, 44, in 2009, and "their relationship moved pretty quickly," an insider told Us. The actress was not photographed in public between May 6, 2009 and April 20, 2010, when she and morgan went public with their romance at an L.A. film premiere.
