Here's a plot twist we didn't see coming! Grey's Anatomy's former star Jeffrey Dean Morgan welcomed a baby boy with One Tree Hill alum Hilarie Burton -- a few months ago!
Morgan, 44, and Burton, 27, apparently started dating in 2009, and "their relationship moved really quickly," a source told Us Weekly.
Burton divorced One Tree Hill assistant director Ian Prange in 2008, while Morgan ended his engagement to Weeds star Mary Louise Parker that same year.
Morgan has a 5-year-old son with actress/producer Sherrie Rose -- a child he reportedly didn't know existed until last year. "He's shocked and surprised, but he wants to be in the child's life," a source has said about the paternity discovery.
