"You might be wondering and asking, 'Carrie, why is your tour starting in May?'" she teases. "Well ... yay!" she exclaims as the camera pulls back to reveal the balloon and her baby news.

"Mike and Isaiah and I are absolutely over the moon and excited to be adding another little fish to our pond!" she shares. "This has just been a dream come true, with album and with baby news and all that stuff. We're just so excited, and just so glad that you guys can share in this with us."
