Lily Allen goes incognito in a black face covering and hooded top as she takes a power walk in London after celebrating 18 months of sobriety

One could be forgiven for failing to spot Lily Allen as she made her latest appearance in London on Thursday. 

The singer’s instantly recognisable features were well concealed beneath a large black face covering and two hooded tops during a stroll through upmarket Knightsbridge. 

Lily, 35, added a thick black fleece to her to her notably casual look, while white gym leggings and Nike trainers rounded things off.

The star appeared to be enjoying a power walk through the central London retail district after celebrating 18-months of sobriety. 

Lily has been open about her addiction battle and has been honoured with a special key-ring from the Narcotics and Alcoholics Anonymous fellowship for successfully  reaching the important milestone. 

In posts on her Instagram, Lily shared an image of the key-ring given to mark momentous dates as well as a selfie showing her holding the fellowship gift over her eye.

Embossed on the key-ring’s grey leather was the message: ‘Clean and serene for eighteen months.

Lily shared a shot while holding the token alongside a gushing caption reading: ’18 months clean and sober today. Would recommend!’

The milestone comes weeks after Lily revealed she debated trying  heroin when she ‘hit rock bottom’ during her 2014 supporting stint on Miley Cyrus’ Bangerz tour.

The singer spoke to DJ Fat Tony on his The Recovery podcast about her sobriety journey, including her rock bottom, as she touched on the tour and how she felt – turning to drink, drugs and prostitutes. 

She said: ‘I was supporting this girl who was much younger and more attractive than I felt. I was thinking: “I think I have got a drinking problem. And none of this acting out is working any more. Maybe I should try heroin.”‘

She then turned to drugs to lose weight after climbing to 14st, adding: ‘I started taking a drug which is like speed to lose the weight and I got addicted to this drug because it made me feel invincible. And then I ended up on tour in America supporting Miley Cyrus…

‘It was when she was doing Wrecking Ball – it was a highly sexualised tour. I had just spent the last three years pushing babies out. It couldn’t have been less what I felt like. I had never supported anyone…

‘I was re-entering this phase of being a pop star again but not doing it on my terms any more. I was supporting this girl who was much younger and more attractive than I felt. I just started acting out in all manner of ways.’
