Next up on "Heat index" our ABC exclusive with Taylor swift. The pop megastar setting social media on fire on Monday. In fact, take a look at these Twitter trends and they are still trending right now. Taylor swift is, just many related to her revealing a new southern music video and album and then after her huge live announcement I was able to sit down with the seven-time grammy winner. She took the digital world by storm. Along with our partners at Yahoo! Connecting with fans around the world. We have people from Brazil to Canada to Norway. Reporter: And bringing many so of her most loyal fans swauled swifties together for three exciting announcements. I have a new song I'm going to play you in like 30 seconds. This album is called "1989." I think it's time we should just play the music video. ? Baby I'm just gonna shake shake "Shake it off" it off ? ? heartbreak is gonna break break break ? ? and I think it's gonna fake fake fake ? ? baby I'm just gonna shake shake it off ? It's so fantastic. We know why you wrote it of your lyrics are telling but it's so applicable to anyone and everyone. Who were you talking to and what is your message in the song? The message in the song is a problem I think we all deal with and an issue we deal with on a daily basis, we don't live just in a celebrity takedown culture. We live in a takedown culture. People will find anything about you and twist it to where it's weird or wrong or annoying or strange or bad. You have to not only live your life in spite of people who don't understand you, you have to have more fun than they do. I like that. That's a great way to look at it. So you shake it off and you shake your booty. You can shake really anything. There's so many things, hair, hand, hips, ankles. I watched the video. It's fantastic, by the way. How great is the video? You put a lot of work into it. Three days of shooting. Yes, we did do three case of shooting to get that exquisite dance performance from me but it was so fantastic. 24 is something, a song when I heard it just now, it sounded like that song that you wanted played at the end of a wedding. Oh, my god, yes. That is what I wanted it to be. It's like the last dance, yes. That is so -- did somebody tell you I said that. No, no one told me to say that. Stop. That's so cool you said that. Yes, because it's like what you want the deejay to play at the end of the night. We were talking about that in the studio -- I said we need drums that make even the person who's having a terrible night at a wedding -- and she's like I'm not in the mood to dance and it comes on, oh, this is my song. This is my song. That's the dream. We all see how important girlfriends are to you. Uh-huh. And you love to post pictures on instagram, social media and you're with people who are also in successful creative endeavors. How do you choose your friends? I choose my friends based on people who I have things in common with, I think. Or people who challenge me. Honestly I think that there's something really inspiring about being around people who know what they want, people who are passionate about something. You want to be around like smart, exciting people. I think that just -- that brings you up. She has a lot of friends. She also has a lot of fans and it's great because at the end of that music video she brought in a hundred of her fans and they were all dancing along with her and the most amazing part about it is they kept it a secret for two months. They couldn't tell anyone that they were in it and she didn't make them sign any waivers or any -- and they dit. They kept her secret for her. That's how devoted they were to her and get this amazing appearance and a really -- isn't that such a -- Great fun. You brought out the best -- I want to ask how old is she again. She's 24. It's amazing. She's so wise I think she's had to grow up really fast. That's what happens when you grow up in front of a national -- actually a worldwide audience of you take a lot of flack and I loved her message. Have more fun than the haters. She's an awesome role model. Great job. I loved ha. I loved her and she was a pleasure and just so much fun and I'm so rooting for her on this new album because I love the name of it, "1989." What a good year, right? We all remember it fondly. Maybe gio doesn't. You were 4. 4. You know what -- "1989." Taylor swift. That's true. She was born in 1989.
