Dressed in a black leather dress and donning a shoulder-length hair cut, a teen-aged Kim can be see channeling her inner Posh Spice in the vintage photo.

“I'm so Thankful that me & my friends were the Spice Girls for our high school talent show! The Spice Girls got me through a lot!” she wrote on Thursday, adding the hashtag #ForeverThankful, which was quite appropriate for the Thanksgiving holiday.

Kim, now 35, also shared a snap from the talent show itself, and she clearly got into her role!
