The 30 Rock star took to Twitter to show off his beautiful little girl, writing, "Here is MAVEN SONAE MORGAN at 2 weeks y'all!!! @MeganWollover," and tagging his fiancé model Megan Wollover in the post.
Maven is the first child for Tracy and Megan. The actor already has three sons with his high school sweetheart and ex-wife Sabrina Morgan.
The cute snap shows Maven swaddled in a brown blanket, staring straight at the camera and wearing a purple flower headband.
She is pictured lying down on a purple throw, with her hands peeking out of the blanket.
Megan shared the same photograph on her account, posting, "My little mama--- Miss Maven, a pic from her newborn pics @ 2 weeks old :-)."
Tracy again showed his delight on Twitter at the birth of his daughter on 1 July, posting, "Its A GIRL!!!!!" on the day.
