Congratulations are in order for '"NCIS" star Michael Weatherly and his wife Bojana. The pair welcomed a (not-so-small) baby boy in Los Angeles on Tuesday.

"Beautiful Bojana give birth to 10lb Liam Weatherly today, the most important day of the week," the actor tweeted Tuesday, before plugging his CBS show complete with a hashtag.

The duo, who wed in 2009, also have an 18-month-old daughter, Olivia, and Weatherly is dad to a 17-year-old son, August, from a previous marriage.

Since Liam weighed in at 10 pounds, here's hoping Bojana got an equally large push present!

Leave your congrats for the couple in the comments below.
