Jeffrey Dean Morgan is a dad again.
"Their relationship moved really quickly," a source told Us about their romance, which began in 2009.
While they couple got together in 2009, they only made their red carpet debut last month at "The Losers" premiere.
A source told E! News that Hilarie, 27, told close friends about her pregnancy last summer.
"She told friends about her pregnancy back in August after she had spent a lot of time with Jeffrey on location in New Mexico," the source said of the set where the former "Grey's Anatomy" actor, 41, filmed "The Resident," with his former "P.S. I Love You" co-star Hilary Swank.
The son is the first child for Hilarie and the second for Jeffrey.
Last year he learned he had a 4-year-old son with Sherrie Rose, an actress and producer
