Mick Jagger’s ex wife Bianca Jagger, 77, is almost unrecognizable at the splashy Dior show

Bianca Jagger was almost unrecognizable at the Dior show in Paris on Monday.

The 77-year-old ex-wife of Rolling Stones crooner Mick Jagger was wearing a new black bob hairstyle that looked extra poufy.

The former Studio 54 fixture – born Blanca Pérez-Mora Macías – mingled with other greats Catherine Deneuve and Monica Bellucci.

Bianca wore her black hair in a 1950s style with little curls at the ends and a bouffant puff on top.

The beauty added ruby red lipstick and black eyeliner as she looked as glamorous as ever.

The star had on an white coat that went almost to the floor. Underneath were off white silk pajamas with black piping.

She smartly added pink and white sneakers as she looked a bit ladies who lunch as she carried a matching purse from Dior, the same model Princess Dior used to carry.

Bianca was married to Mick between 1971 and 1978 and the pair had a daughter named Jade, who previously admitted that having famous parents was a ‘hindrance’ as she often receives ‘awful’ comments from people.

The 50-year-old 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 demoralizing 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!’
