The actress, 33, beamed as she hung out with her famous friends, flashing her long legs and toned figure in the sparkly number.
Emily showed off her outfit on Instagram before the show, pairing the silver minidress with strappy shoes to complete her look.
The star wore her blonde hair back off her face in a high ponytail and fixing her make-up to ensure her eyes and cheekbones popped.
Due to the cut of the dress the blonde beauty decided to ditch her bra to make sure it fitted just right.
Sharing a snap of her cuddled up to DJ Calvin Harris, the comedian wrote: “I look like a proud mum showing off her successful kids.”
Emily then raised a drink to the camera to toast a no doubt incredible set by the musician.
Later on, the Inbetweeners star revealed she was also backstage at David Guetta’s set.
Emily has been in Ibiza to shoot the latest campaign for her collaboration with high street brand New Look.
Earlier in the week she shared a stunning beach snap in a plunging white dress.
Showing off a golden sun-soaked glow, Emily tied her blonde locks back and wore a yellow flower in her hair for an added summery touch.
The I’m A Celebrity star previously showed off her incredible figure in an orange bikini during her Ibiza getaway.
