A video has hit the Web showing Grey’s Anatomy newcomer Chyler Leigh, who plays Meredith’s neurotic half-sister Lexie, kissing her older brother.

Internet-savvy Grey’s fans have discovered footage of the then 15-year-old star’s inaugural movie role in 1997′s Kickboxing Academy. In an odd choice of casting, the film’s producers cast her brother, Christopher Khayman Lee, as her love interest. Not only is he her love interest – they also have a few kissing scenes. EW! And just in case you were wondering, YES they really are brother and sister. I confirmed it on IMDB, here.

This video gives me the hee-be-jee-bees.

See for yourself!
