Michael Weatherly is a proud papa once more!

Weatherly's wife of two and a half years, Bojana Jankovic, gave birth to the couple's first child together Tuesday.

The delighted dad took to Twitter Wednesday afternoon to share his and Jankovic's happy news with fans.

"Gentlefolk of Twitter and elsewhere, Bojana and I are proud to announce the arrival yesterday of Olivia Weatherly! #SpecialAgentWeatherly," the NCIS star, 43, wrote.

Baby Olivia is Weatherly's second child; the actor also has a sixteen-year-old son, August, with his ex-wife, soap star Amelia Heinle.
