Country singers Miranda Lambert and Blake are definitely familiar with baby rumors. Married since 2011, the media has often speculated as to whether or not the couple is in fact expecting.

Shelton decided to have a little fun with this expectation on Twitter Tuesday. "Ok.. Ok.. Guess I'll go ahead and let the cat out of the bag," he admitted. "We're expecting!!! Yep!! We're expecting @carrieunderwood to have a baby!!"

Surely the musician caused his fans' hearts to skip a little beat before they got to the Carrie Underwood part, though he was sure not to leave them hanging for too long.

Blake Shelton Returns to His Roots With New Album

Underwood, who happens to be the Somethin' Bad duet partner for Shelton's wife, announced on Monday that she and her husband are expecting. Underwood, who has been married to NHL player Mike Fisher for four years, had a little fun with her own announcement when she posted it with her dogs on Twitter Monday.

Unlike Shelton, it seems Lambert chose to take a more serious route in congratulating her fellow artist. "Big congrats to my friend @carrieunderwood (aka Louise) on her big news!!!! So happy for her and Mike!" she tweeted Tuesday.

Perhaps this news will give Shelton and Lambert a reason to consider having children of their own. After all, it might be nice for the little Underwood to have a little Lambert to play with out on the road.
