"I'm sorry if I seem distracted," Styles, 21, told the crowd at the Apple Music Festival. "My sister's here on a date, and I'm trying to keep an eye on it."
The sister in question is 23-year-old Gemma, and Style made sure to tell her to "behave" while out.

"This is very Harry," One Direction expert and Entertainment Weekly Digital News Editor Amanda Michelle Steiner told PEOPLE. "He also likes to point out pregnant ladies and pantomime as if he too is pregnant. And he calls out people on dates all the time, one time telling a married couple to kiss to embarrass their teenage daughter."
One Direction announced that their new album, Made in the A.M., Tuesday. It's now available for pre-order in advance of its Nov. 13 release, and the group is whetting appetites for it with a new tune, "Infinity."
