A spokesperson for the actress has confirmed that she gave birth to a son named Kellen William Patino, according to People.
Kellen weighed in at 6 pounds at the time of his arrival on Thursday April 2.
The newborn boy's arrival comes nearly three years after the birth of Stables and Patino's older son Kendrick Kurt on September 2012.
Patino and Stables, 37, are celebrating their own tenth wedding anniversary this year.
Stables is perhaps best known for her recurring roles in "Two and a Half Men", "Greek" and "The Exes" on television.
