Newcastle United players met the group ahead of a training session in what will be a busy week for the club.
They play Benfica in the Europa Cup on Thursday night, then face local rivals Sunderland on Sunday.
After the meeting, United right-back Danny Simpson posted a photo of Harry Styles in which the One Direction singer was posing topless, showing his tattoos.
Simpson called him a "proper safe guy".
