You might think Jason Derulo has a booty fixation.

Just look at the lyrics of his two hits — "Talk Dirty" and "Wiggle," which have been mainstays on the soundtrack of this summer.

"You know what to do with that big fat butt: wiggle, wiggle, wiggle," he sings on the latter song, featuring Snoop Dogg.

He gets universal on "Talk Dirty" featuring 2 Chainz: "Been around the world, don't speak the language/ But your booty don't need explaining."

Derulo 24, talked clean when he called last week from his Miami home to discuss his performance Friday at Macy's Glamorama fashion show in Minneapolis, his fiancée Jordin Sparks and his playful, booty-shaking music.

Q: What appeals to you about performing at Glamorama?

A: I grew up — my sister, my mom, my brother — we were like a Macy's family back in the day. They had nice clothes at real prices. They were like a staple here in Miami. It's really cool to be part of something special like this.

Q: What are you going to wear?

A: When I perform, I usually wear one-of-a-kind stuff that's custom made. I'm sure it will be something fly. I'll probably wear a jacket but not for too long and then have a sleeveless shirt under it.

Q: Describe your own fashion sense.

A: If it's daylight, I do a lot of sporty wear. A lot of baseball caps, gym shorts, a lot of sleeveless shirts. For performances, I've been doing something that has more of an edge to it. I've been wearing a lot of snakeskin, crocodile, stuff with studs in it. I've been wearing a lot of white. My sense of fashion changes all the time. When somebody looks at you, they should be able to tell what kind of personality you have. My personality is a little loud.

Q: What sparked you to write "Wiggle"?

A: Just having fun, man. With this album, I really experimented a lot. "Talk Dirty" and "Wiggle" came off with that happy, party spirit, that deep down-and-dirty spirit. The album has lots of different sounds that you don't hear on pop radio. Like "Wiggle," the main instrument is recorder. Remember in elementary school how you learned how to play the recorder? It really stands out. You hear 'Talk Dirty" with the saxophone. It was something you would never hear [on pop radio], but you're hearing it a lot more now. My next song is "Compass," and the main instrument on that is trumpet. It's talking about how beautiful my girl is, but in a way you don't normally hear it. 'I hear symphonies when she walks in the room,' 'I hear trumpets in my head.' I'm relating to her like Kanye West songs, Coldplay songs, Katy Perry songs.

Q: Who is the better dirty talker — you or Jordin?

A: Ha ha ha. I don't know, man. I'm not sure.

Q: Speaking of Jordin, in your song "Marry Me," you promised to marry her when you "get your money right." Judging by your recent success, you got your money right. So when's the wedding date?

A: Ha ha. I get that question a lot. We've been together almost three years now. It's all about the right timing.

Q: What did it feel like to have both "Wiggle" and "Talk Dirty" in the Top 10 at the same time?

A: It's crazy. And at the same time the Florida Georgia Line song was like No. 14. [Derulo performed on a remix of their hit "This Is How We Roll."] For those couple of weeks, it was surreal. I've had a lot of pinch-yourself moments and it never gets old.

Q: What's your workout regimen to keep those fabulous abs?

A: I'll usually start with the Insanity workout. It's really vigorous. I use that as a warm-up. Then I'll do 30 minutes of abs. Then we'll do the show. It's vigorous. Then after the show, we'll do like 500 pushups. Then off to bed.
