Beyonce feels like a "teenager" in Topshop.

The 'Formation' singer has always loved going to the high street chain's flagship store in London because it is one of the few places she can shop by herself without being bothered.
She said: "I've been shopping at Topshop for probably 10 years now. It's one of the only places where I can actually shop by myself.
"It makes me feel like a teenager.
"Whenever I was in London, it was like a ritual for me - I'd put my hat down low and have a good time getting lost in the clothes."
Beyonce has teamed up with the retailer for her new leisurewear collection Ivy Park, and was inspired to design the garments after having daughter Blue Ivy four years ago.
She said: "I think having a child and growing older made me get more into health and fitness.
"I realised there wasn't really an athletic brand for women like myself, or my dancers, or my friends.
"Nothing aspirational for girls like my daughter.
"I thought of Ivy Park as an idyllic place for women like us."
It was important for the 34-year-old star to be very hands-on with the range, much to the surprise of Topshop boss Sir Philip Green.
She told Britain's ELLE magazine: "I reached out to Topshop and met with Sir Philip Green. I think he was originally thinking I wanted to do an endorsement deal like they'd done with other celebrities, but I wanted a joint venture.
"I presented him with the idea, the mission statement, the purpose, the marketing strategy - all in the first meeting. I think he was pretty blown away and he agreed to the 50-50 partnership."
