One of the photos displays Kendrick holding a joint, and in another, a pipe.
In the movie, Kendrick played the role of Jessica Stanely, the best friend to the main character,.
The 27-year-old actress made the candid confession during an appearance on Ellen DeGeneres's talk show on Friday, admitting that she was so focused on how her nipples might look that she actually berated the crew after they made the set too warm.
Most of the pics were taken during a Halloween party where Kendrick is dressed up as a sexy angel.
