Stephanie Pratt is looking fine in a teenie red bikini.
The Hills star was playing in the ocean while in Hawaii on a gorgeous day.
It was her birthday and she just turned 26, so she partied it up by going surfing!
She cut her knee pretty badly!
She posted the pic (above) to twitter and wrote:
"Surfing party favor lol"
Way to laugh it off, cause that looks pretty painful!
Maybe next time just stick to splashing around on the shore.
