Mick Jagger's ex-wife Bianca looks effortlessly chic in a black leather trench coat as she arrives at Costes hotel during Paris Fashion Week

Mick Jagger's ex-wife, Bianca, looked effortlessly chic in a black leather trench coat as she arrived at the Costes hotel during Paris Fashion Week on Friday.

The former Studio 54 fixture, 80, born Blanca Pérez-Mora Macías, looked incredible as she arrived in a white shirt layered under a black lace top.

She paired her bold garments with black trousers, black shiny shoes and toted her belongings around in a Christian Dior handbag.

Bianca was married to Mick from 1971–1978, and together they are parents to daughter Jade, 53.

Bianca is Mick's first and only legal wife after she met Mick in France and quickly got pregnant with their daughter Jade.

They wed in May 1971 when she was four months along. The ceremony was in Saint-Tropez.

Together, Bianca and Mick were the toast of NYC in the 1970s as they party hopped with Halston and Diana Ross.

In May 1978, she filed for divorce on the grounds of his adultery with model Jerry Hall, Bianca later said, 'My marriage ended on my wedding day.'

Their daughter Jade previously admitted that having famous parents was a 'hindrance' as she often receives 'awful' comments from people.

The jewellery designer said: 'I mean it is a hindrance, the other day I was googling something and I found an awful, tragic piece about me saying that 'she just can do whatever she wants' and it's very demoralising after you've worked all your life to try and achieve something.'

Jade did admit that she admired her parents for their successful careers, as it has given her something to 'look up to' and strive to achieve in her own life.

She explained: 'But also, obviously, seeing what my family have done always makes you look up to something higher that is almost unachievable.

'I try to bring myself down from thinking that's my goal, because I think that can leave you with heartache, because I'm certainly not going to be jumping around on stage in the pouring rain. I have my limits!'

Mick is now in a relationship with fiancée Melanie Hamrick, but last year she revealed they are in no hurry to marry.

Giving an unprecedented look into her relationship with the rock star, the former ballerina, 37, also said they will move to London permanently next year so they can enrol their eight-year-old son, Deveraux, in school.

Melanie confirmed she has been engaged to Mick for three years in an interview with Paris Match when asked how long she has been wearing her engagement ring.

And talking of marriage, she said: 'Maybe one day, maybe not. We are so happy in our current life that I would be too afraid to change anything. I don't know what to call it, maybe simply happiness.'

The secret to their happiness, she claimed, was supporting each other and being there for each other.

Melanie and Mick met in Tokyo in February 2014 when the Stones were on tour.

At the time, the rock star was in a long-term relationship with fashion designer L'Wren Scott, who died by suicide in March that year.

She says it wasn't love at first sight, as she quipped: 'Maybe a spark, but nothing incredible like: 'I'll make you lose your mind, and we'll travel the world!' We didn't even exchange phone numbers.'

Melanie recalled that Mick was in a relationship at the time, so they only spoke again five months after that, thanks to a mutual acquaintance who gave him her number.

The rocker sent her a text message asking whether she'd like to have coffee together, which led to them meeting again in Zurich.

Melanie recalled an early memory from childhood, saying: 'My mum would also sometimes hum "I can't get no satisfaction" when I asked for an ice cream I hadn't earned. I would reply, "stop mum, it's so boring".'

Her penchant for older men preceded her relationship with the famous rock star. When she was 19, she started dating Cuban dancer José Manuel Carreño, who was 38 at the time.

Melanie insisted she doesn't care what people say or think about her 44-year age gap with Mick because she's happy, healthy, and not hurting anyone.
