While fans of Kelly Clarkson are understandably giddy about the singer's pregnancy, there is one person whose excitement just can't be beat, and that's Grandma Reba -- known to most of us as superstar Reba McEntire

On Tuesday (Nov. 19), Clarkson spilled the good news, letting the world know that she is expecting her first child. Soon after, McEntire tweeted her excitement to her step daughter-in-law, and you can practically hear the squeal in her southern twang just from her words.

"Narvel and I are thrilled to pieces for you, Brandon, Savannah and Seth!!! Love, Grandma Reba and Granddad Narvel," McEntire -- who is the stepmother of Clarkson's new husband Brandon Blackstock -- writes.

We wouldn't be surprised if Grandma Reba has already picked up a few gifts for the upcoming babe, whose due date has not been revealed. The fiery-haired country singer may have more and more opportunities to be a grandmother, as Blackstock already has two kids from a previous marriage and his blushing bride has freely admitted that she wants lots of kids.

“I never wanted kids before, but now I want, like, five,” Clarkson shared while sitting down with Jay Leno earlier in November.

Congratulations to McEntire on her upcoming grandbaby and to Clarkson and Blackstock on their first together. May there be many more!
