Back in 2013 Dolly's goddaughter Miley Cyrus had come under some criticism for, lets say, excessive twerking. I don't know if it was to poke fun at Miley for it, or maybe to ease some of the pressure on her, but as a guest on Queen Latifah's talkshow, Dolly performed a humorous rap talking about her large breasts and how she works and twerks them. This of course while simultaneously bouncing them with her pectoral muscles.
So, I guess Dolly had come up with a good excuse to turn everyone's attention to her breasts, and to literally and figuratively flex them in front of an audience...
