The 18-year-old singer said he always wanted to get rid of his mother when she used to go on the road with him, but now he pines for her help, reported Femalefirst.
"I do miss her, yeah, I mean especially now being 18. Before when I was round her all the time, like, every day, I was getting sick of her and I would look forward to her leaving, like, 'Yes mom's leaving tomorrow!'
"And now I'm like, 'When is mom coming back?' Because I don't see her that often so you know it's funny how those things change," he said.
The 'Baby' hitmaker says he rarely gets time to go out partying because he is always so tired due to his work commitments.
"I don't really go out... I'm super busy, so by the end of the night I'm super tired... We don't go clubbing, we just hang out low-key and just chill."
