Kendall Jenner, Jourdan Dunn And Gigi Hadid Upstaged By The Backstreet Boys At H&M Balman X H&M Catwalk Show

Kendall Jenner, Karlie Kloss, Jourdan Dunn, Victoria’s Secret Angel Alessandra Ambrosio and the Hadid sisters were joined at the Balmain x H&M catwalk launch by the "Balmain Army's" surprise new recruits... The Backstreet Boys.

And Gigi Hadid and Jenner couldn't hide their excitement:

The New York show marked the official launch of the collection, which will cost a fraction of the Balmain main line when it goes on sale on 4 November.

The FROW was every bit as star-studded as the catwalk, with Rosie Huntington-Whiteley, Alexa Chung, Lewis Hamilton, Ne-Yo, Ellie Goulding, Diane Kruger and Kendall's sister Kylie Jenner taking in the outfits, before singing along to Backstreet classics.

It wasn't only Nick Carter and co who wowed the crowds with their moves. The show began with a choreographed dance routine, (which we've been practising in the office all morning):

The show also saw Gigi Hadid's sister Bella return to work less than two weeks after revealing she's been suffering from Lyme disease.
