Kate Moss misses premiere for her own film Moss & Freud which chronicles her drug-fuelled party girl youth - as actress Ellie Bamber steals the spotlight

Kate Moss was a no show at the premiere of her new biopic Moss & Freud at Selfridges in London on Tuesday, allowing actress Ellie Bamber to steal the show.

The film explores the unlikely bond between Kate and artist Lucian Freud, who together curated Naked Portrait 2002. 

It sees her doppelgänger snorting drugs and leading her half-dressed chauffeur into a raunchy London sex club before getting caught in a near-fatal car accident. 

Lucian is played by Derek Jacobi in the film, which features the real-life Kate (played by Ellie) as an executive producer. 

Despite working alongside the movie, Kate skipped the celebrations ahead of its release this Friday.

Appearing on The One Show earlier in the day alongside her co-star Derek, Ellie discussed what it was like to play Kate.

She said: 'It was really frightening and I really felt like I had a responsibility to do her justice. 

'The voice was something I really spent a lot of time stewing over. I think it was something that was really important to me.

'Her laugh in particular was kind of a gateway into her and so I spent a lot of time with an amazing vocal coach and we worked on the voice.'

Kate lent clothes from her wardrobe for the film including the iconic blue gown she wore to her 30th birthday party.

Ellie added: 'I am pretty clumsy. I was terrified. I had James Brown, a friend of Kate’s for a long time, who did all the costumes. That dress is so precious. It is fashion history.'

Kate was famously dubbed 'Cocaine Kate' when she was photographed snorting the substance in 2005 but has since turned her life around and opts for a clean-living approach. 

Now sources have claimed the model's unwavering support for the film is the closest she has ever got to confessing to her wild past.    

'She has supported the creation of the movie from day one and continued to have input and assist the team behind it'.

'Which means that Kate has seen the contents and not only given the nod to them remaining, but continues to back the producers. It's the closest she has got to confessing to some of the racier parts of her life'.

They went on to tell The Sun: 'Though, of course, she can argue that the drama is only based on a true story, and not necessarily the whole truth'.

The Daily Mail have contacted Kate Moss's representatives for comment. 

After she accepts the idea, in the ethereal, moody and glitzy teaser, the extremes of their relationship were displayed, with the pair seen to argue over her dedication to their project while later enjoying blissful giggles. 

Derek's Lucian is seen saying to Kate: 'Could you imagine anything more beautiful? I think a painting - but do you have time? I'm quite aware of what a busy life you must lead', after which she agrees to undertake the task: 'Lucien, I like the idea of truth.'

The distinguished artwork captured a nude, then 28-year-old Kate while she was pregnant with her daughter Lila, who she welcomed with ex Jefferson Hack.

Sexy and raw, the image, which was painted by Lucian - then 80 and at the time 52 years older than Kate - showcased the model in a way she'd never been seen before.

The lead up and process of the painting is teased in the trailer, as Lucian demands: 'If I were to paint you I need absolute commitment', before viewers later see him becoming enraged at Kate for missing their sessions. 

Standing in front of his canvas, he roars: 'You are late, do you treat all of this as some kind of game? Three evenings a week is all I ask and to be on time'.

Kate is quick to hit back, as she is seen jabbing images of herself in a glossy magazine, saying: 'This, this, some of them are long-term relationships!' in relation to her relationships with designers and photographers. 

She then muses: 'The painter must think of everything he sees as being entirely for own use and pleasure is that what I'm here for? To be used by you'. 

A slow-moving clip sees the duo dancing at a recreation of Kate's legendary 30th birthday bash, which was held at Claridge's hotel in 2004, took on the theme of F Scott Fitzgerald's book, The Beautiful And Damned.

The movie's initial release in October was met with mixed reviews, however next month the film will be opened to a wider audience.  

The result of Lucian's artwork of Kate was groundbreaking, with the painting fetching a whopping £3.9million at an auction in 2005.

Lucian and Kate's time together established a one-of-a-kind friendship, and the model would later describe him as ‘the most interesting person’ she'd ever met.

So fierce was their bond, prying eyes have long questioned whether they shared something more than just friendship.

The German-born painter - also famed for his modern and selfie-esque painting of The Queen in 2001 - passed away aged 88 over a decade ago.

Moss & Freud, aims to explore his life and art, and focuses strongly on how the 90s superstar came to be his beloved muse.

Kate's arrival on the scene in the early 90s signified a new era of models, joining the likes of Naomi Campbell, Cindy Crawford and Linda Evangelista as some of the biggest names in the industry.

Meanwhile Lucian Michael Freud, born in 1922 in Berlin, Germany, was by then a renowned painter and draughtsman who specialised in figurative art; his work on human subjects such as friends, family and lovers earned him the reputation as one of the foremost 20th-century English portraitists.
