Lily Allen, 34, took to the stage at the Governors Ball Music Festival on Sunday night in New York City.
The British singer arrived in an eye-catching pink suit to perform a string of hits in the sunshine before whipping off her jacket to reveal a see-through top underneath.
Her pink ensemble was embellished with images that paid tribute to her English heritage including several red roses, which are the national flower and are often used to represent England in sport.
Her blazer was also colourfully decorated with what appeared to be the river Thames and part of the London Underground map.
On one arm Lily had an NHS sticker and a picture of a pint of beer and while the other side carried the Three Lions football emblem.
During the show, the Smile hitmaker, who wore bold blue eyeshadow and sparkly nails, removed her top to reveal a lingerie-style garment underneath.
The songstress exposed her breasts in the lacy sheer bodysuit which left little to the imagination.
Lilly appeared to be in good spirits as her belted out hits at the gig and was pictured with a huge smile on her face.
Also set to perform on day three of the Randall’s Island festival were The Strokes, Charlie XCX and Nas, however bad weather meant several sets were cancelled following and even the headline act were unable to play their set.
