GMA HOST Ginger Zee HAPPILY announces to audience the arrival of her New Baby, BUT what she and her Newborn have to endure night after Night Touches everyone’s Heart.

Ginger Zee just became a mom for the second time — and the ABC chief meteorologist admits the birth of her son Miles Macklin is still sinking in.

“Still in disbelief I’m surrounded by boys but couldn’t be happier,” Zee, 37, says in this week’s issue of PEOPLE, sharing exclusive photos of her new family of four.

The new mother of two announced her son’s arrival on Twitter Feb. 9, sharing a photo of Miles’ foot the following day alongside his birth stats: 8 lbs., 7 oz., and 21½ inches long.

“Ginger and baby are doing great,” a source close to Zee told PEOPLE at the time.
