Reba McEntire's son Shelby Blackstock and daughter-in-law Marissa are preparing to welcome their first child together, and they revealed their unborn son's name as part of their baby shower.

Shelby and Marissa plan to name their baby boy Archer. Based on some of the photos from the shower, it seems like they could be planning "Archie" as a nickname.

Shelby and Marissa Blackstock chose a very on-brand theme for their baby shower: An all-access, behind-the-scenes event celebrating baby Archer's "Welcome to the World" tour.

Guests got their very own VIP passes to celebrate Archer Blackstock's first big "tour" starting in October 2026 — aka his expected due date month.

They were also invited to sign a special custom record plaque, which read "Archie Blackstock: A Star is Born."

Look closely at the bottom left corner of that plaque. One message to the baby-to-be appears to read, "We're gonna have so much fun!" signed "Grandma Reba."

Other shots from the party include a photo of mom-to-be Marissa posing with her bump against a red carpet-style backdrop, framed by blue, black and gold balloons including one in the shape of an electric guitar.

She also shared a photo of a cake her mom brought for her, which reads "It's a Boy!" in blue lettering against white frosting.
