The couple's date night was interrupted by paps amid reports of their relationship troubles (Lily hasn't been wearing her wedding ring recently and has been meeting up with her ex-boyfriend Seb Chew) and unsurprisingly, there were no smiles on show.
But perhaps an evening of wining and dining in London's most sought-after celebrity hangout is just what Lily needed? She's back in the UK after touring the US with Miley Cyrus this summer.
As for Lily's outfit? The 'Hard Out Here' singer wore a fluoro green and blue jumper dress with Nike Air Jordans and her wear-it-everywhere transparent Ashish x Topshop backpack.
She's still working the pinky-purple hair dye too after making a statement on stage with Miley last week.
What to know what they got up to? Take a look at this video Lily posted on Instagram of her twerking with the American popstar. She wrote "@mileycyrus #thankyou #notfair #bangerz #sheezus"
Miley and Lily together on stage - so far, so OTT. But it was always going to be.
Does this mean there's a real collaboration on the cards? Music or fashion or both? Watch this space - we'll keep you posted on everything #bangerz #sheezus related.
