That's one way to stay warm!
As frigid temperatures hit New York, Zoe Kravitz and Penn Badgley
cuddled up at the Cinema Society & Artistry after party for Warm Bodies
at the Penthouse at the Hotel on Rivington.
"Penn ordered drinks for both of them and Zoe sat on his lap for much of the night," an onlooker tells PEOPLE.
The couple chatted with the film's stars Nicholas Hoult – who recently split
from Golden Globe and Screen Awards Guild Award winner Jennifer Lawrence
– Teresa Palmer and Analeigh Tipton.
Kravitz also stopped to chat with The Big C
's Gabourey Sidibe before the night was over.
