HGTV “Fixer Upper” stars Chip and Joanna Gaines, seen here a year before their Magnolia Market at the Silos opened to become a major Waco attraction, will feature former First Lady Laura Bush and former NFL star Tim Tebow in the series' final season.

Lest attention should lag in its hugely popular series "Fixer Upper" with Waco's Chip and Joanna Gaines, HGTV dropped a sizable tease about the final season in David L. Haynes' HGTV blog.

The fifth and last season, which starts Nov. 21 (one month away and counting), will feature former First Lady and fellow Texan Laura Bush as a guest — she's a big fan, her daughter Jenna Bush Hager told the "Today Show" — and former NFL quarterback Tim Tebow (Chip's a fan, we presume).

It's been a fairly high profile fall for the Gaines with announcements of their new Target product line, their final season and Chip's new book, "Capital Gaines: Smart Things I Learned Doing Stupid Stuff," whose promotion took the couple to New York City last week. Also ahead in upcoming months will be the opening of their Magnolia Table restaurant, the former Elite Cafe, and publication of Joanna's cookbook, "The Magnolia Table Cookbook."

No word on what Laura Bush or Tebow will be doing on their appearances — I don't think the Bushes' Crawford ranch is due for a reno and as tempting as it is to imagine Tim taking a knee in front of the Silos, it ain't gonna happen - but I'm sure we'll find out in due time. Magnolia Time.
