Queen of country Dolly Parton is the latest star to make a cameo appearance in a Super Bowl commercial -- and she's teaming up with her goddaughter, Miley Cyrus.
In a new two-part commercial for T-Mobile about 5G phone technology which debuted on "Good Morning America" Friday, Parton films a spoof public-service announcement about helping 5G phones and then gets a little help from Cyrus.
"When I see a problem, I am going to fix it. America's got a serious problem, so I'm going to get it off my chest. 5G phones trapped on limited 5G networks. But you can make a difference," she says in the spot, adding that she wants phones to "be able to shine their brightest like me. I have my own theme park."
Cyrus calls Parton to ask how she can help the phones.
"You've got a voice, Miley! Use it! Do it for the phones!" Parton tells her.
Cut to Cyrus singing a special song: "Let's do it for the phones, they do so much for you. When they're out there all alone, there's something we can do!"
Parton teased the clip on Wednesday, which shows her telling her protégé over FaceTime, "You got a voice, Miley, use it." As Cyrus appears struck by inspiration, Survivor's 1982 hit "Eye of the Tiger" plays in the background.
In a brief montage, Cyrus toils over song lyrics, plays the piano and scribbles notes before asking out loud, "What would Dolly do?" The teaser abruptly ends with a message telling fans to tune in on Sunday, Feb. 13, to catch the big-game day ad in full.
