Rita Ora has switched on Oxford Street's Christmas lights - saying "it means a lot to me".
The "Switch On" event, in London's West End, marks the start of the festive shopping season.
X Factor stars Matt Terry and 5 After Midnight performed live throughout the evening.
Anywhere singer Ora, 26, said: "London is my home so switching on the Oxford Street lights means a lot to me.
"I used to love coming to Oxford Street to see the Christmas lights when I was younger so this means even more to me."
Over 750,000 bright white LED bulbs and 1,778 baubles decorate the mile-long stretch of Oxford Street, "taking inspiration from falling snowflakes".
