Donald Faison is best known to Scrubs fans as Turk (aka JD's best friend for life).
And now he and wife CaCee Cobb – who are already parents to one-year-old Rocco – have announced they're going to be parents again via Instagram.
Donald took to the social networking site with an adorable photo of his son with the words "I'm a big brother" printed across his T-shirt.
Check out the cuteness for yourself:
N'aww!
CaCee and Donald tied the knot in 2012 and they welcomed baby Rocco to the world just one year later.
At the time, Donald tweeted the happy news to his followers.
SHOULD MOTHERS BE BANNED FROM TAKING PLACENTA PILLS AFTER GIVING BIRTH?
He wrote: "Yesterday @caceecobb and I welcomed the most amazing little boy into our lives! Oh Happy Day!"
His wife retweeted his message with the addition, "The happiest day of my life".
Donald, 40, is already dad to Sean, 17, from a previous relationship, twins Dade and Kaya, 15, and Kobe, from his marriage with ex-wife Askey.

While the gender of this little bundle of joy remains unknown, one thing is certain - Scrubs co-star and BFF Zach Braff will be VERY excited.
After all, he already loves being an honorary uncle to little Rocco.
Congratulations to the happy couple!
