Dekker Edward Gosselaar was born Sept. 30, and joins big brother Michael, 10, and big sister Ava, 7, in the Gosselaar household. 

"We are overjoyed with the new addition to our family," Mark-Paul tells Us Weekly. "We are madly in love with our little boy. He is healthy and just perfect -- all we could ask for."  

Mark-Paul and Catriona married in July 2012 after a year-long engagement. His two older children were a result of his 15-year marriage to Lisa Russell, whom he divorced in June 2011.
