Jennifer Garner has no idea what became of the iconic dress she wore in 13 Going on 30.
The Daredevil actress famously wore the multicoloured number for a scene in the 2004 movie in which her character Jenna Rink does an impromptu dance to Michael Jackson's Thriller.
But while the dress remains popular among fans, in an interview for Glamour, Jennifer revealed that she didn't keep the cute outfit.
"Here's a crazy fact, this dress, I didn't keep it. It didn't go anywhere, it just went into a warehouse," she said. "Nobody knew it was going to be a big deal. Who knows where it ended up? Sadly, I don't have it."
However, Jennifer noted that the dress can be seen on a "background player" in old episodes of Sex and the City.
Elsewhere in the chat, the star credited customer designer Susie DeSanto with dreaming up so many great looks for the movie.
"She has such a beautiful sense of character, of colour, of fun, of fashion, and she brought all of that into play on 13 Going on 30," the 51-year-old continued. "Anything I could have dreamed, she dreamed bigger, and anything that I could have wanted she had that plus 10 better options in every fitting. So, we just had a blast together."
