According to an insider, Katherine Heigl has informed Grey’s Anatomy producers that she and her husband Josh are trying to start a family, so that her pregnancy can be written into the show’s storyline.

“They are ready for a child,” says the insider. “She gave her TV bosses a heads-up, just in case she gets pregnant soon.”

Katherine and Josh reportedly also plan to adopt a child from Korea (where Katherine’s sister was adopted from), but Korean law requires that a couple be married for three years prior to adopting. Since they’ve only been married for a year and a half, they’re trying for a biological baby first. Says an insider, “They are hoping for a big family.”
