The 21-year-old star, who has recently split from singer Ariana Grande, does not think that he could be the kind of guy who acts "really cool," reported Contactmusic.
"I don't know I really like the chase. I like to work hard to impress a girl," he said.
"But at the same time I'd be too nervous to be like 'Yeah, she likes me, so I'm going to act really cool.' Also, if I thought she didn't like me I'd be like, 'I'm too scared to chase!'" he added.
"Maybe a tiny bit of a hint. Before I've had a small hint and thought 'Yeah? Ok...' then straight after I'm like, 'Oh God, this is terrible. I'm gonna embarrass myself!'" he said.
