Earlier this year, former model Stephanie Seymour said that Kendall Kenner and Gigi Hadid were 'bitches of the moment' while others denied their status as 'true supermodels'.
However, one model who vehemently disagrees with them is Coco Rocha.
In a post to Instagram yesterday, the 5ft 11inch beauty showed her support for the sisters' continued success on and off the catwalk.
She captioned the image: 'I've been doing this modeling thing for a minute and I'd just like to say, for the record, @gigihadid and @bellahadid are the REAL DEAL. #Supermodels are back and I never thought it was possible.'
The news comes after the pair's inimitable SS17 runway success, walking the likes of Marc Jacobs, Max Mara, Tommy Hilfiger, Ralph Lauren, Moschino and Michael Kors, from New York to Milan.
In the past two years, Gigi has appeared on several internationally-renowned magazines including ELLE and Sports Illustrated and launched her own collection with Tommy Hilfiger titled 'Tommy X GiGi'. She has also been dating singer Zayn Malik for over a year.
Meanwhile, Bella is currently dating Canadian singer The Weekend (real name Abęl Tesfaye) and has modeled alongside her sister on several occasions, most notably in Balmain's Fall 2015 ad campaign, and recently won GQ's 2016 Model of the Year award.
Not bad for girls who aren't really supermodels, then...
