Did Brad Paisley just spill the beans about Carrie Underwood expecting a boy?! During their opening monologue, the two co-hosts joked back and forth about Underwood's baby-to-be and Paisley may have blown it for the songstress!

It all started when Paisley joked to Underwood, "And we're pregnant!" which caused the blonde mom-to-be to interject, "Brad, I don't remember you being there."

Paisley then responded, "Carrie, you can't keep me out of this child's life," and started to beg Mike Fisher's wife to reveal to him whether she's expecting a boy or a girl. A persuaded Underwood then whispered in his ear and Paisley exclaimed: "I know something you all don't know. Suck it TMZ!"

After making a few jokes about Taylor Swift and Renee Zellweger, the co-hosts revisited the topic while announcing Garth Brooks. "Hey, we could name him Garth," Paisley told Underwood, alluding that she's having a boy.

"What are you doing? What is wrong with you?" Underwood told the country crooner, before confusing the audience further by adding a "just kidding," while concluding, "Well you kept that secret for a whole two minutes, hashtag Brad blew it."
