We gotta love an actress with a hearty sense of humor, fun-loving spirit and ability to laugh at herself.

Jennifer Lawrence is one of those starlets, proving that she can let her hair down and roll with the punches. Whether she tripped while having walked onstage to accept her Academy Award or took cheesy modeling pictures during her awkward teen years, she knew how to laugh it off.

And apparently, she knows how to make others laugh up a storm. At this year's MET Gala on May 6, the leggy starlet slid down a handrail while walking outside the star-studded location. It just so happened that someone captured her funny and daring action on tape and uploaded it to YouTube.

While Lawrence is dressed in a floor-length, elegant, charcoal evening gown, she just jumps onto the rail with an adventurous, mischievious look on her dazzingly made up face.

If you concentrate hard while watching the clip, what is also great to see is the split-second glimpse of gut-busting laughter from another actress, Marion Cotillard. Though some bystanders and others around Lawrence did not notice the moment, Cotillard erupted in chuckles.

Check out the clip below! Go ahead and smile, too.
