Shailene Woodley was seen passionately kissing her White Bird in a Blizzard co-star Shiloh Fernandez.
The 21-year-old actress and the 27-year-old actor play love interests in the dramatic thriller about a woman whose life goes into tumult following her mother's disappearance.
Apparently Shailene and Shiloh are also intimate in real life, as they were witnessed locking lips and flirting heavily at the Sundance Film Festival.
While partying at the Hyde Lounge the couple became closer throughout the evening.
"They danced until 2 a.m. and ended up making out at the end of the night," a source told Us Weekly magazine.
Shailene's career is also booming at the moment.
After receiving a Golden Globe nomination for her work in George Clooney's 2011 drama The Descendants, the actress has been piling on projects.
Shailene is currently filming The Amazing Spider-Man 2, which also stars Jamie Foxx, Emma Stone, Sally Field and Andrew Garfield.
Her sci-fi action film Divergent is currently in pre-production and is slated for release in 2014.
