Chad Lowe is ready to reveal the moniker he and wife Kim chose for their new bundle of joy.

"My wife & I want to thank everyone again for the kind words of congratulations on the birth of our daughter Fiona Hepler Lowe!" the Pretty Little Liars actor, 44, tweeted Tuesday, Nov. 20.

Lowe and his wife welcomed Fiona (who joins big sister Mabel, 3) in Los Angeles Nov. 15. Just a few days before Kim gave birth, the star opened up to Us Weekly about how his family was prepping for the new addition.

"It's a very special time. I'm excited and Mabel is super excited," he told Us. "We've been waiting for this!"

"[Mabel] knows she's got a big job," Lowe added. "She's got a lot of things to teach her sibling."
