*Tamera Mowry-Housley  is now officially a first-time mom.

The actress and her husband-of-18-months, Fox News correspondent Adam Housley, welcomed son Aden John Taylor in Los Angeles on Monday (Nov. 12), two weeks after Mowry’s due date.

“We are so happy! He is healthy, happy, strong, beautiful, and our families are so excited to have another grandchild, cousin and nephew,” Tamera tells In Touch magazine.

Tamera’s twin sister Tia Mowry and her husband Cory Hardrict welcomed their first child, Cree, in June 2011.

Congratulating her twin on Twitter.com, Tia writes, “Yay!!! I can finally now say I am an auntie…!!!! Cree now has a play date! He is beautiful!”
