We have a special guest who stopped by recently. The one, the only, you know her well, miss piggy. She was here to tell us about her star-studded new project, featuring the likes of lady gaga and elton john and some of their closest muppet friends. You know, it is thanksgiving. I'm going to tell you all what i know that I'm giving thanks for today. Moi? Yes. Yes. I am definitely thankful for you. Of course, you have. I'm thankful for tonight's holiday spectacular. Starring moi. Yes. That is right. Starring the lovely and talented miss piggy. And that other almost as famous superstar, lady gaga. Lady who? Exactly. Our cameron mathison went behind the scenes for their shoot. It wouldn't be thanksgiving without the muppets. ♪ I don't want to be alone forever ♪ ♪ but I love gypsy life ♪ Reporter: On tonight's special, kermit and lady gaga perform hits from her latest album. ♪ wow. I'm so excited because me and kermit are performing together. Reporter: Yes. We are wonderful. Everything about this show has really been exciting because it's been a dream come true of mine, really. I love the muppets so much. Reporter: Your fans, you call the little monsters. That doesn't necessarily apply to you, kermit. We certainly have that in common. We have little monsters in our lives. And probably some big ones, too. Do you call your fans little frogs? No. No. But I could. I like the idea. Maybe it's a good idea. I like tadpoles. Reporter: It's a holiday special. So, I didn't realize I would be stumbling into a big celebrity love triangle. Is kermit your favorite growing up? I know it's awkward because he's the one sitting right here. He was my favorite. And he knows because I had a crush on him for a long time. Wow. Reporter: How is miss piggy dealing with the obvious chemistry between you two on this production? That's interesting to talk about. It can be touchy. Next question. Reporter: I hit a nerve. I definitely hit a nerve here. Probably not a good thing. This show is going to be so great. And I'm so proud to be working with you. But we still have a finale to plan. Reporter: I talked to kermit and lady gaga together. And they have a special chemistry, I noticed. Really? Reporter: It's nice. Yeah. There's nothing like old-fashioned fun, family and some more superstar music for the holidays. For "good morning america," I'm cameron mathison, abc news, los angeles. ♪ Oh gaga and the jets ♪ ♪ bennie and the jets ♪ sing it. Yeah. Also tell them when the show airs, miss piggy. It's tonight.
