This week she took to the stage in her signature skater-style pieces complete with lace, jewel tones and plenty of embellishment.
Ella's Saturday night outfit was a real show-stopper. We loved her Alice + Olivia dress - priced at a blow-the-budget £475! - and Topshop shoes, £75. But it was Ella's River Island neck piece, £85, which really made the outfit. Vintage-esque and seriously bling... we want!
On Sunday night, she opted for a more colourful get-up, pairing a purple skirt from ASOS, £30, with a Boohoo jumper, £20. Her belt from Oasis, £16, and leg-lengthening Topshop shoes topped off her simple yet stylish look.
And how good does Ella look without make-up?! Us, jealous? Never!
She also showcased some high street gems when she attended the launch of the Kardashian Kollection for Dorothy Perkins earlier in the week. This time she shone in metallics with a silver Topshop dress, £55, and a ladylike jacket, £59, bag, £25, and shoes, £45, all from Dorothy Perkins.
We predict a style icon in the making!
