Lily Allen has revealed her £8K-a-week trauma centre stay inspired her to get a tattoo about 'accepting pain' after  estranged husband David Harbour moved on with new girlfriend Ellie Fallon. 

The singer, 39, recently returned to work on her Miss Me? podcast after reportedly checking herself into the facility and telling friends she was close to a nervous breakdown amid the couple's split.

Lily called time on her marriage to David in December after discovering he was using the celebrity dating app Raya.

Speaking with pal Miquita Oliver, 40, on the latest episode of their podcast, Lily explained that she read a book about 'self compassion' during her stay. 

Confessing: 'It really stood out for me and I might even get it as a tattoo, it was "suffering x pain = resistance"'.

While Miquita was left speechless by the wise words, Lily continued: 'You have to sit with the pain and confront the pain and accept the pain,'.

'Love the pain, caress the pain, you got to be like "This is painful" it's OK for things to be painful and for you to feel pain, bat it away, if you're batting it away, you're resisting it and that is the cause of your actual suffering'. 

It comes after The Mail on Sunday revealed that the Hollywood actor was dating aspiring model and actress Ellie who at 27 is 22-years his junior.

He is believed to have known the blonde for several months and it was she who accompanied him on his New Year trip to India, where he was spotted by fans with a 'mystery woman', according to an insider.

Friends say that Lily is aware of the romance and is 'very upset' after seeing provocative pictures of Ellie smoking one of Harbour's favourite brands of cigar.

The social media shot of Ellie, who has 10,000 followers on Instagram, was uploaded in October – several weeks before Harbour and Lily decided to separate.

Ellie is believed to have met Harbour in the US city of Atlanta, where the actor has been living for a year to film the fifth and final series of Stranger Things. 

A source said: 'Lily is aware of the romance and has been very upset.

'Seeing the picture Ellie posted of herself smoking a cigar, taken weeks before Lily and David called it quits, has convinced her that Ellie and David had been seeing each other before they split.

'After all, how many 26-year-olds smoke cigars?'.

It comes after Lily has accused US doctors of 'driving her crazy,' after they prescribed her strong medication that had a vastly negative impact on her mental health.

Speaking during another podcast episode she revealed that after being prescribed antidepressants by an American doctor last year, her mental health took a severe turn for the worst. 

Lily said: 'The medication that I was on last year sent me f***ing crazy. So I've had to change. I've had to come off of that medication and start a new one.

'And that was a big part of where things became really unmanageable for me.

'Before I came to America, my friend Olivia said to me, "Just be really careful of the doctors over there and the prescriptions that they prescribe you for things".

'But I really think I was done a bit of a number on by one of the antidepressants I got put on and it really did not work for me.

'There were other things going on too. But yes, the pills weren't helping.'

Lily also defended her decision to check into a trauma centre, away from her daughters, admitting it was 'getting harder to be there' for her kids'.

In her first podcast episode back after her stint in the centre, she admitted she didn't want her children to 'have to prop her up' as she battled 'emotional turmoil' following her split from David.

In her first podcast episode back after her stint in the centre, she admitted she didn't want her children to 'have to prop her up' as she battled 'emotional turmoil' following her split from David.

Saying: 'People think I hate my children. I really don't. I absolutely adore my children and I'm in a situation now where I really have to be my strongest self for them. 

'I felt like it was getting harder and harder for me to be able to show up for them in the way that they need me to.

'It was a big decision to have to leave them for a few weeks to go and focus on myself but ultimately it was for them so that I can get us through this bit. I needed some help to be able to do that.'

She continued: 'I don't want them to ever feel like they have to prop me up. None of this is their fault and it's my job to support them and make them feel safe and secure, and I just don't think I was able to do that because of the emotional turmoil that I was in at the time.

'But I do feel like I am now. I'm not saying that I'm 100% there or getting it 100% right or that I ever will but I'm definitely in a stronger place.'

Lily shares her two daughters Ethel, 13, and Marnie, 11, with her ex-husband Sam Cooper.
