The New York Daily News has this item about "Grey's Anatomy" cast member Chyler Leigh:
Hard-core "Grey's" fans have unearthed a 1997 B-movie, "Kickboxing Academy," that Leigh made when she was just 15. In it, the actress' love interest is played by her real-life brother, Christopher Khayman Lee.
And yes, there are kissing scenes. Couple of 'em.
(What? You don't remember Christopher as the red ranger in "Power Rangers in Space"?)
The sibling snogfest seems to have been uncovered first by "Praise Anatomy," a highly entertaining fan vlog about the show. You can check out the clip under the YouTube user "TeamAtrox."
