Diaper duty continues! Noah Wyle and his wife, Sara Wells, have welcomed a baby girl together, his rep confirms to Us Weekly. The couple's daughter, Frances Harper, arrived on Monday, June 22.

The ER alum's love announced her pregnancy when she debuted her baby bump at Vanity Fair's Oscars afterparty back in February.

This is the first child for the pair, who married last June at their Santa Barbara ranch. Wyle, 44, also shares son Owen, 12, and daughter Auden, 9, with ex-wife Tracy Warbin.

Wyle, though often quiet about his personal life, opened up about fatherhood and his Father's Day expectations back in 2013. "I don't want to put any pressure on my kids to feel like they have to do anything for me," he said on Missouri's Fox local TV station KOLR-10. He joked: "I don't want to put that kind of emotional baggage on them but at the same time I am harboring this secret fantasy that they will do something to show what an amazing father I am."

He also noted that Owen loves to visit him on set of his TNT show Falling Skies. "To him his dad has the best job in the world. I run around with a machine gun all day and shoot aliens. So my street cred with his third-grade class is pretty high," he gushed. "He looks at me like a hero, which makes me go back each season."
