Ace's future best buddy has arrived!
"Yesterday @caceecobb and I welcomed the most amazing little boy into our lives! Oh Happy Day!!" Faison tweeted Friday.
"The happiest day of my life," Cobb added, also retweeting her hubby's sentiment.
No other details were immediately available, including the little guy's name, so we're waiting on that for now.
Once it was general knowledge that both Cobb and Simpson were expecting at the same time, however, they were free to be super-psyched for each other out in the open. Simpson threw her pal's baby shower and Faison called the pair "a good team" back in February.
It's "great for those two" to be pregnant together, the former Scrubs star told E! News.
While their son is Cobb's first child, this is baby No. 5 for Faison, who has three sons and a daughter from previous relationships.
J.D. and Turk forever!
