Four years later!

Former Grey's Anatomy guest star Jeffrey Dean Morgan recently found out that he has a child with actress-producer Sherrie Rose, according to Us Weekly.

"Yes, I have a 4-year-old son with Jeffrey," Rose confirmed to Us.

The actor reportedly had no clue until this celeb gossip report broke today. Kind of a d!ck move by Sherrie Rose in that case, no? What gives, lady?

A source said the Watchmen star learned of the boy a few weeks ago and has since met him: "He's shocked and surprised, but he wants to be in the child's life."

Rose is an ex-girlfriend of Jeffrey Dean Morgan, who is also known, gossip-wise, for his longtime relationship with his former fiancee, Mary-Louise Parker.

They began dating in 2006 after meeting on her hit Showtime series, Weeds, where he played her late husband, but she called off their engagement in 2008.
