Former "Scrubs" star Donald Faison and CaCee Cobb welcomed their son in August, and now they're giving their fans a peek at their little boy.

The baby, reportedly named Rocco, is Cobb's first child and Faison's fifth. It's been a busy year for the couple, who were married at the end of last year.

Cobb's childhood best friend, Jessica Simpson, also welcomed a son, Ace Knute, over the summer.

"They hang out all the time anyway, but now they hang out and talk baby stuff, look at baby stuff online and go shopping for baby stuff together," Faison told People magazine of the pals in February. "Cacee's loving it."
