Morgan and fiancée Megan Wollover are expecting their first child together, People reports.
"I am over the moon excited and just want a happy and healthy baby and a safe delivery for Megan," Morgan, 44, told the magazine.
The actor-comedian plays Tracy Jordan on the NBC comedy, which is airing its final episode Thursday. We just hope that the comedian doesn't plan to consult "Tracy Jordan's Guide to Irresponsible Parenting."
Morgan has three full-grown boys with his ex-wife Sabrina, whom he divorced in 2009 after 23 years of marriage. But this will be the first child for his 26-year-old model fiancée.
Morgan and Wollover announced their engagement on the red carpet of the 2012 Primetime Emmys, but Morgan told E! that he had popped the question six months prior.
So what's he up to after "30 Rock" ends? Morgan is set to launch his comedy tour "Excuse My French" in Kansas this March.
