Sofia Coppola premiered her latest film, Beguiled, at the Cannes Film Festival last night, starring Kirsten Dunst, Elle Fanning, Nicole Kidman and Colin Farrell.

And, in one of the more unexpected moments on the Cannes red carpet, Dunst was photographed tearing up alongside her costars:

While the actress has so far given no explanation for the outburst, Coppola and Fanning's smiling reactions suggest that Dunst was crying happy tears, not ones of distress.

Whatever the cause, all's well that ends well. Dunst wiped away her tears and was all smiles for the group photos.
