In photos: Jennifer Lawrence just wants to have fun

She has her serious moments, but Jennifer Lawrence is also quick to crack a joke and bomb a photo, so we've rounded up her lighthearted moments - and, boy, does this girl love to have fun.

The self-proclaimed klutz, who celebrated her 27th birthday on Aug. 15, has been all over our radar since her meteoric rise to fame as tough-as-nails Katniss Everdeen in the The Hunger Games films, plus an Oscar win (including her famous stumble in pale pink Dior) for Silver Linings Playbook.

Watch the video below for an adorable post-win interview video where Jennifer meets Jack Nicholson for the first time:

Speaking of memorable run-ins, the Kentucky native couldn't contain her excitement at 2015's Comic-Con convention when she bumped into one of her idols, Bill Murray. "I have been, like the rest of the world, a huge fan of Bill Murray for a really long time," the actress said during a press conference at the popular event in San Diego. "Just the fact that Bill Murray knows I exist was part one. Part two, he wanted to speak to me, and then he like, mentioned something about us working together. I'm excited about that. That was cool."

Since splitting from her long-time boyfriend, Nicholas Hoult, in spring 2014, the blond beauty has been enjoying her 20s by hanging out with girlfriends like Taylor Swift and Brie Larson and enjoying romances with Chris Martin and her current boyfriend, director Darren Aronofsky.

The star's professional life is also giving her plenty of reasons to smile. Next up, Jennifer will debut her new thriller Mother! at the Toronto International Film Festival in September and is currently filming another X-Men flick. She is the reigning face of Dior and has penned a movie with pal Amy Schumer.

To mark the ingenue's 27th birthday, we've rounded up some the feistiest photos of the beloved actress.
