Michael Weatherly has become a father again.

The NCIS star and his wife Bojana Jankovic, welcomed a daughter Tuesday. She's their first child. Weatherly already has a 16-year-old son, August, from his previous marriage to The Young and the Restless' Amelia Heinle.

The over-the-moon actor announced the news on Twitter: "Gentlefolk of Twitter and elsewhere, Bojana and I are proud to announce the arrival yesterday of Olivia Weatherly! #SpecialAgentWeatherly."

Nice to see his baby daughter already has her own hashtag.

Congratulations to Michael and family on the new arrival!
