Kendall and Kylie Jenner will have to make space for another diva within the Topshop family as Beyonce is set to launch her new range with the high-street brand in 2016. The Flawless singer has designed an activewear range, which the brand hopes will boost sales following a "challenging" sales period.

Sir Philip Green, owner of Arcadia which houses Topshop, has confirmed the 34-year-old singer, will debut her athletic-streetwear range, Parkwood Topshop Athletic, in April 2016, which is part of a bid to boost sales.

The collection, which will span clothing, footwear and accessories for dance, fitness and sport, will be available in Topshop stores in 20 countries. Green said of the collaboration: "We are developing our distribution globally for the launch of this exciting new brand in spring 2016."

News of the partnership, which follows on from the Jenners, was revealed in October 2014, with Beyonce announcing in a statement: "I could not think of a better partner as I continue to grow the Parkwood business. I have always loved Topshop for its fashion credentials and forward thinking.

"Working with its development team to create and produce a technical and fashion-led collection is exciting, and I'm looking forward to participating in all aspects of this partnership."

Green, 63, added at the time: "We have been looking at this category as fashion-inspired fitness develops, and know that this is right in our customers' heartland. Creating a partnership with Beyonce, one of the most hard-working and talented people in the world, who spends many hours of her life dancing, rehearsing and training is a unique opportunity to develop this category.

"Being partners with Beyonce and her team, who have the greatest creative energy and enthusiasm, is inspiring for all of the team at Topshop. We have much to achieve in just under a year, but we are all up for the challenge, and look forward to delivering athletic streetwear in an inventive and exciting way."
