Being quite the fashionista, Ellie is often a regular on the FROW and last night, she proved her credentials in the style stakes while attending the Erdem showcase in the capital.
Channeling all the sass, the 'Burn' signer made sure everyone's eyes were on her in her fierce getup. Thigh high slit? Check. Slicked back locks? Check. Killer boot heels? Check, check, check!
Posing alongside her boyfriend and McBusted star Dougie, Ellie cut an oh-so-glam figure.
The 28-year-old chose to don a Balmain tiger-print dress and told fans she loved rocking the designer frock for the evening. So much so, that she let it take centre stage, keeping her accessories and beauty look to a minimum.
Ellie tucked her blonde locks back behind her ears in a sleek and straight style, finishing her ensemble with mascara-clad lashes and a slick of lipgloss on her lips.
Not to be totally outdone, Dougie made sure to bring it on the fashion front too.
The guitarist looked effortlessly cool as he teamed a pair of black skinny jeans and a matching tee with a military-inspired jacket. On his feet, he wore a pair of stone-hued boots and styled his famous long locks to the side.
There, the couple rubbed shoulders with the likes of Lily Cole, Suki Waterhouse, and Colin Firth.
Ellie's appearance at London Fashion Week comes after her new track 'On My Mind' recently hit the headlines.
After fans had heard the song, many were quick to speculate that in it Ellie was hitting back at Ed Sheeran.
It has been widely speculated that Ed has written his song 'Don't' about Ellie, and after she included some telling lyrics, Ellie's song has been dubbed as a retaliation. She, however, has hit back insisting 'On My Mind' is about nobody in particular.
In an interview with MTV USA, Ellie said: "People can read into it however they want. It's fun to do that, I would do that too."
"I'm sorry to all the people that want it to be about someone," she added. "It's not, it's like a myth."
