The stars are now interviewing each other on Twitter, and Wednesday (Dec. 19), it was Reba McEntire and her future daughter-in-law Kelly Clarkson. (Kelly just got engaged to Reba's stepson, Brandon.)

There were some of the usual questions: Other acts Reba likes include Trisha Yearwood, Little Big Town, Pistol Annies and Kelly Clarkson, of course.

And then, Reba fired this at Kelly:

“Speaking of the engagement, since you are going to be my daughter-in-law, I’m singing at the wedding, right?”

Kelly: “Obviously! My request is ‘Let’s Get It On’ by [Marvin Gaye]. That’s not awkward, right? :)”

Reba: “We may have to talk about that one later . . .”

Kelly asked Reba if she has ever taken a spin around the track with her professional race car driver son, Shelby.

“Are you on CRACK????!!!! NO!!!! And I don’t plan on it!!!!”

Sensible woman, that Reba.

On Thursday (Dec. 20) at 6 p.m. ET, Miranda Lambert and Sheryl Crow will step up to the Twitter interview plate.
