If the early start wasn't enough to freak the X Factor star out, these two witty fans certainly made sure to give poor ol' Ella a spooking...
Ella stormed to the top of the charts this summer with her debut single 'Ghost' and surprising her outside the BBC studios today were two of her supporters who pulled out all the stops to get their favourite singer's attention.
Donning their best ghoul get up, the fans showed off their sense of humour as they paid tribute to Ella and her recent chart hit.
And impressed with their efforts the 18-year-old was more than happy to pull her best scared-looking face and pose with the pair.
Looking gorgeous in monochrome, Ella wore a sheer black top with opaque panelling, loose-fitted black trousers and a pair of chunky-heeled shoes for her radio appearance.
To finish her look, Ella teamed her outfit with a funky black and white bomber jacket, featuring a mesh cut out design.
The starlet was at Radio 1 as a guest on Nick Grimshaw's breakfast show and was promoting 'Glow', her second single from her album Chapter One, that will be released next month.
Last week, Ella unveiled the music video for 'Glow' where she smoulders in black and leather. Speaking about her new track, Ella said: "'Glow' will definitely surprise lots of people. It's a sound no one is expecting from me."
As well as setting her sights on chart success in the UK for a second time, Ella has ventured to the States recently in a bid to crack America.
Performing 'Ghost' on Good Morning America last week, Ella showcased her vocal talents in both New York and LA.
Phew - that is one busy schedule!
Ella's new single 'Glow' is set to be released next month on 14 September.
