Taylor Swift is deep thinker: Ashton Irwin

5 Seconds of Summer star Ashton Irwin feels singer Taylor Swift is a deep thinker.

Irwin, however, added Swift, 25, seems to be a "little destructive" to him, reported Female First.

"She feels a little destructive to me. I think it's interesting, I think it's cool, she's a deep thinker. She has a lot of songs about some messed up relationships. I think some good songs would come out of it," Irwin, 21, said.
