"They're thrilled to be adding to their brood," says a rep for Getty. The couple are already parents to son Cassius Paul, 6, and daughters Grace, 5, and Violet, 3.
"I love kids. I love having a big family," Getty told PEOPLE at the recent William S. Paley Television Festival in LA. "I think the more the merrier – big happy home of, you know, little punks running around."
Getty, 32, plays loyal son Tommy on the ABC drama. He also has a band, Ringside, whose concerts attract a large celebrity following in Los Angeles.
Rosetta, 37, owns a children's fashion line, Rosetta Millington (her maiden name), and launched a high-end women's line, Riser Goodwyn, this year.
