Lily Allen sports a grey tea towel on her head and sunglasses as a disguise while going undercover at Notting Hill Carnival

Lily Allen cut a demure figure as she went ‘undercover’ to enjoy Sunday’s Notting Hill Carnival.

The 38-year-old singer used her best disguise to blend in with the two million people who attend the West London street festival, which takes place annually to celebrate Britain’s British Caribbean community.

Keeping a low profile, Lily covered her head with a gray tea towel and shielded her eyes with gold-rimmed sunglasses.

On her Instagram, Lily delighted fans with her quirky outfit as she danced with friends to the street performers.

In another photo, she showed off her chic sense of style and enviable figure in a Fendi denim jacket and matching sky blue wide-leg jeans with a tie-die crop top.

Lily carried a £3,300 denim clutch, also designed by the luxury Italian fashion house, adorned with flowers.

To complete her look, she kept it casual with white sneakers and looked sensational in the festival-ready outfit, which showed off her toned stomach and arms.

Captioning the day out on her social media, she wrote, “Dipped in the carnival.”

Flamboyant revelers marked the opening day of the Notting Hill Carnival in style, taking to the streets of London in their thousands to attend the festival – with police declaring the event passed ‘without major incident’ despite 85 arrests.

The festive spirit kicked off early as festival-goers began to fill the streets of West London as the crisis broke down before the festivities kicked off, which are expected to attract more than two million visitors this weekend.

On the first day of the party, revelers celebrated the ‘J’ouvert’ – a Caribbean tradition that marks the ‘opening of the day’ and the beginning of the Carnival.

Attendees were seen enjoying the paint-splattered ceremony — and a police officer was even pictured joining in on the fun by spraying a bottle of purple paint over the crowd.

The event, which took place 55 years ago, saw huge crowds take to the streets of Notting Hill in what is the second largest gathering of its kind after Brazil’s Rio Carnival.

Lily’s performance comes after a candid interview in which she admitted she was “addicted” to her fame while being “out of her face” on drugs and alcohol.

The singer reflected on her struggles with her vices before getting sober and described the early years of her career as “a bit of a blur.”

Now four years sober, Lily has given up music to pursue an acting career and is currently starring in a West End production of The Pillowman.

Speak with The New York TimesShe said she went through a turbulent time in 2018 promoting her album No Shame, which left her “disinterested” in the industry.

She said, “From when I was 18 to about four or five years ago, it just kind of feels like a blur because I was literally just off my face the whole time.

She added, “I used fame too — that was an addiction in itself.”

Lily will wrap up her stint on The Pillowman next month, adding, “I still get to play with the human experience, but I don’t have to put my heart on my sleeve as much” as I do in her music.

Rather, she reflected on her four years of sobriety in March, after settling down in New York with husband David Harbor and her two daughters.

During this morning, Lily said, “It’s weird. My life has changed so much. I’ve been clean and sober for four years, I’ve got a new husband, we’re sorting our lives out in America.’

Lily has always been open about her drinking and drug abuse, especially when she released her memoir My Thoughts Exactly in 2020.

In 2018, she came under fire for glorifying drug use after admitting to sniffing a line of ketamine at the 2008 Glamor Woman Of The Year Awards.

Describing what happened, she said, “Someone at the Glamor Awards once gave me a line that I thought was cocaine, but it turned out to be ketamine. I got kicked out of the Glamor Awards (passed over a fence) for being in a hole.”

She added: “Obviously I couldn’t speak or direct the driver, so my assistant instructed the occupant of the car behind to ‘follow that cab.’ I believe the occupant was @chattyman. I have no idea what happened next.’

The mother-of-two recently spoke about the challenges she has faced in her demanding stage role that kept her away from her loved ones during its three-month run.

Via Instagram, Lily admitted that she struggled with loneliness as a result, exacerbated by the presence of her children at a summer camp in the United States.

She wrote, “Hello Monday. 1 month to go from The Pillowman. I miss my home, miss my bubbas who are both at summer camp, I haven’t even spoken to them in 2 weeks!

“Tired and lonely, but the Banya always manages to stir my blood and cheer me up.”
