Jessica Simpson's BFF CaCee Cobb is pregnant again!

Cobb and husband Donald Faison are expecting their second child together, the couple announced Tuesday, Oct. 21, via Instagram.

Cobb, 36,  and Faison, 40, each took to the image-sharing site and shared a super adorable photo of their 14-month-old son Rocco flashing his sweet smile with an animated bow tie and balloons and the words "I'm a big brother!!" typed across his shirt.

During her first pregnancy, Cobb joked that she kept her husband constantly on his feet. "[I tell him], 'I need you to move this, I need you to move that. Pick up this, help me with this,'" she shared to People in June last year.

Faison, who plays Phil Chase, a sports agent and a womanizing divorced man, on TV Land's sitcom "The Exes," added, "My character at work is a ladies' man. When I go home, I'm a b-. I'm her b--."

Simpson, for whom Cobb formerly worked as a personal assistant, welcomed her second child, Ace, with husband Eric Johnson in June last year. And less than two months after that, Cobb gave birth to Rocco.

"Yesterday @caceecobb and I welcomed the most amazing little boy into our lives! Oh Happy Day!!" Faison wrote on Twitter at the time.

"The happiest day of my life," added Cobb, who also retweeted Faison's post.

Once it was revealed that both Cobb and Simpson were expecting at the same time, the two had openly been super-psyched for each other. The "These Boots Are Made for Walkin'" hitmaker even threw a baby shower for her pal, E! News reported.

Faison, who called the duo "a good team" back in February, told the entertainment and celebrity news site that it's "great for those two" to be expecting ogether.

Faison and Cobb tied the knot in Zach Braff's backyard in December 2012, Us Weekly reported.

While the couple's upcoming bundle of joy is going to be their second kid together, it will be Faison's sixth child. Aside from Rocco, the "Robot Chicken" voice actor is already father to Kobe, 12, twins Dade and Kaya, 14, and Sean, 17, from his previous relationships.
