Kylie Jenner -- I Make A Hell Of A Zombie ... But Not Much Of An Actress

Kylie Jenner has finally made her music video debut ... and while she pulls off the zombie look perfectly, she still needs some work in the acting department.

Tyga dropped his video for "Dope'd Up" Saturday and he and his 18-year-old gf star in what feels like a Michael Jackson's Thriller wannabe. The video starts in the back of a Rolls Royce (naturally) with a normal looking Kylie and ends with her in full zombie garb.

We're guessing Jenner was asked to act like she was scared in the beginning of the video ... but the performance is just about as exciting as watching paint dry.

You'll remember, TMZ got pics of the two reliving their not-so-distant high school memories while shooting the video earlier this month.
