The Miz and his wife Maryse Ouellet have announced the birth of their second child together, a baby girl. "We've got the whole world in our hands. Welcome, Madison Jade Mizanin," The Miz wrote on Instagram on Sunday alongside a photo of the newborn's foot being held. Madison was born on Friday and weighed seven pounds, 15 ounces. The Miz, 38, and Maryse, 36, announced in February that they were expecting their second child. The WWE power couple and "Miz & Mrs" reality show stars are already parents to 1-year-old daughter Monroe Sky. The Miz, real name Michael Mizanin, and Maryse, became husband and wife in February 2014. The Miz is set to host "WWE Smackdown's Greatest Hits" alongside Charlotte Flair on Friday on Fox at 8 p.m. ET. The hourlong special will showcase some of the greatest moments from WWE's long-running blue brand before "Smackdown" switches to Fox on Friday nights starting on Oct. 4.
