    Somehow, Jennifer Garner and Christa B. Allen are not the same person.

    Christa B. Allen, who played Young Jenna in 13 Going on 30, has an excellent TikTok account, which she frequently uses to make content based on the iconic movie.

    13 Going on 30 looks recreated for 2020. I can’t believe it’s been 15 years since we made this movie 🤯

    She previously went viral by almost perfectly re-creating Young Jenna's '80s outfit.

    This year for Halloween, she outdid herself by taking on one of Adult Jenna's looks worn by Jennifer Garner.

    And, let me say, it is so spot on.

    If you did a double take because you thought for a moment you were looking at Jennifer Garner, I do not blame you!

    Before you ask, yes, Christa also gave us her own version of the film's "Thriller" dance number.

    #duet with @d3mstreet HAPPY HALLOWEEN!! 🧟‍♀️ I am STILL a terrible dancer but this was so fun! 🤣💕

    As if that weren't enough, Christa also took a second to perfectly respond to a slightly shady comment on her costume, quoting an original line from the movie.

    Clearly, Christa is the winner of Halloween 2020, don't you agree?
