When Taylor Swift pays big bucks for a private gym session,

that’s just what she expects,

even if it means kicking a fellow pop star

out of the vicinity.

After completing his session, Bieber left with his crew, all the while not knowing that Swift was the one who requested they exit stage right. Once he left, the remaining gym members were also asked to leave.

A source at the gym insisted that Swift had an appointment with a trainer where she specified she’d like to train alone in the facility, and that the incident was not personal. Swift has, however, made her feelings known about Bieber’s manager, Scooter Braun, as the two have been engaged in a music business feud over her master recordings for months.
