Delevingne confirmed the news over the weekend, tweeting that she is "so excited for the #VSFashionShow! Had my fitting yesterday and am so happy about my outfit. Be prepared, be very prepared."
Dunn hasn't exactly let that cat out of the bag, but a source told The Daily Telegraph that she'd also be in the show. Dunn flew into New York over the weekend without specifying why she made the trip. A recent update put her "in a mini bus on my way to Winchester," but she previously promised that she'd be back in the Big Apple "in a bit."
If Dunn does walk in the show, she and Delevingne will share the runway with a lineup of models including Miranda Kerr, Lindsay Ellingson, Erin Heatherton, Adriana Lima, Behati Prinsloo, Candice Swanepoel, Doutzen Kroes, Lily Aldridge, and Alessandra Ambrosio. Ambrosio has been selected for the honor of wearing this year's $2.5 million Floral Fantasy Bra during the show.
