Robert Pattinson knows how to do low-key well.
The actor quietly slipped into R&B singer The Weeknd's listening party last night at Hollywood's No Vacancy. Wearing a blue hoodie, Pattinson and three pals were escorted in through the back.
They spent most of the Hennessy-hosted evening hanging in an upstairs balcony before taking off at about 2 a.m.
