The 19-year-old 'Lightning Bolt' singer took to the makeshift stage at the 'Burberry Acoustic Presents Jake Bugg Live' at the British fashion label's flagship store in Regent Street.
Burberry's creative director Christopher Bailey launched Acoustic Live to promote UK musical talent, and the brand's advertising campaigns last year included up-and-coming British musicians and bands including Marika Hackman and The Day Dream Club.
Bugg was joined by Burberry model 20-year-old Cara Delevingne at the bash, who wore a Burberry beige and black striped blazer over a peplum blue corset with a pair of black leather trousers and electric blue velvet heels.
The pair left the party before hopping into a waiting car and heading off together.
Bugg recently angered One Direction fans by claiming the boyband won't last in the music industry, telling Q magazine: "One Direction? The young girls will grow up and forget about 'em.
"There's only [one direction] they'll be going after that, isn't there? Down. I'm interested in which songs, artists, will be remembered in 50 years' time."
Other guests included Pixie Lott and her Burberry model boyfriend Oliver Cheshire, and Fish Tank actor Harry Treadaway.
