'Catwoman' Jocelyn Wildenstein and her fashion designer fiancé Lloyd Klein got all dressed up to hit the town in Miami on Tuesday.

The famously on-off couple held hands as they showed up to the opening of Julie Miles Boutique at COMO Metropolitan Miami Beach. 

Jocelyn, 80, wore a black off-shoulder top with a glittering embellishment on the front with form-fitting leather trousers and cowboy style boots.

Through the years: The socialite earned the nickname 'Catwoman' as a result of her exaggerated feline features, which have become much more pronounced over time

Her blonde locks were salon fresh and she carried a small handbag and her Covid-safe mask in hand. 

Lloyd wore a white T-shirt emblazoned with a photograph taken by the late Terry O'Neill with cropped black trousers and trainers as he cosied up to his bride-to-be. 

The couple have been engaged since 2017 when Lloyd presented the New York socialite with a 32-carat diamond ring which is reportedly 'worth millions.'

They started dating over 15 years ago and had planned to marry in 2018, but are yet to make it down the aisle. 

Wildenstein rose to fame in the Nineties during a high-profile divorce from art dealer Alec Wildenstein, receiving over $2 billion from her husband in the split. 

Lloyd has denied reports that Jocelyn has had surgery.

'I don’t understand the whole press and the Catwoman thing, because Jocelyn always looked like that,' Klein said.

'She never really did anything to change her face. I have pictures from 16 years old where she looks exactly the same as today.'

In January 2019, Lloyd unveiled his new face exclusively to DailyMailTV after undergoing a facial rejuvenation procedure following his years-long battle with cancer.

Klein was diagnosed with lymphoma in 2013. He had a tumour the size of an orange removed from his armpit and underwent three rounds of gruelling chemotherapy.

In 2017, he was told the cancer had spread to his spine and liver and he only had six months to live.  But Klein told DailyMailTV in 2018 that he was in remission.

He said: 'I knew at that moment I had to focus on what it is most important in my life - and that's Jocelyn. For me it was so important to recognize that commitment by making her my wife.

'She has always been there for me, throughout our ups and downs. I cannot imagine living a single day of my life without her.'

The French fashion designer said the intense chemotherapy destroyed his face, so he turned to Wildenstein, his girlfriend of 15 years to help look for a way to restore his face.

Klein, who has designed clothes for Nicki Minaj, Pink and Joan Collins, told DailyMailTV: 'I'm happy, very happy with the procedure. It's revolutionary.

'You go in and have the procedure done, 15- 20 minutes then you go home. As days go by you see the results. It's incredible.' 

In 2017, Jocelyn and Lloyd hit headlines as they dismissed claims of a late night fight. 

They insisted they injured themselves having passionate sex after a dish of beef bourguignon exploded. 

Neighbours had heard screaming coming from their apartment and police arrested both after they arrived at 1am to find the shattered casserole dish on the kitchen floor, bruises to Wildenstein's neck and arms and a cut to Klein's forehead.

Canadian-born couturier Lloyd said he had raced to the shower to wash the scalding broth off his legs where he says he slipped and fell, suffering a small cut to the forehead.

Wildenstein joined him the bathroom to check he was OK but before long the couple had moved to the bedroom and started to have sex.

They told DailyMail.com that neighbors overheard their noisy lovemaking and wrongly leapt to the conclusion that Wildenstein was being attacked.

'I burned my legs when the dish exploded and I went to the shower to put water on it,' Klein said.

Rows: Wildenstein and Klein's 15-year romance appeared to be over in December 2016 when Jocelyn sank her claws into his face in a now-notorious catfight

'I must have made a lot of noise, I was panicking, but Jocelyn came into the bathroom to see that I was OK and one thing led to another.

'I slipped and cut my forehead because everything was very wet, but it was no big deal, a tiny cut.

'We went into the bedroom and had great, passionate sex. The neighbours probably heard all this and assumed someone was being murdered.

'A few minutes later the security came into the apartment uninvited and walked right in on us in the bedroom.

‘I can see why it looked like a fight with the food on the floor and the little bit of blood – but I can assure you it wasn’t that, 100 percent.’

Mother-of-three Wildenstein insisted the bruises on her neck and arms referenced in the criminal complaint were completely innocent.

'Lloyd can be very passionate, he can be a little rough,' she laughed. 'That's something I enjoy otherwise I would not have been with him all this time.

Wow! In 2017, Jocelyn and Lloyd hit headlines as they dismissed claims of a late night fight. They insisted they injured themselves having sex after a dish of beef bourguignon exploded

'None of this would have happened if the cooking pot had not exploded. I have never seen anything like it. He burned himself and when I went to help him we took a shower together.

'The security did not want to hear any explanations. They reached their own conclusion. It was a horrible time.’

Police arrived minutes later and the couple were taken to different Manhattan hospitals before being booked into jail on misdemeanor assault charges. 

The charges were dropped and they reconciled. 

In December 2016, Wildenstein was arrested for sinking her claws into Klein’s face and scratching him with scissors in a now-notorious catfight.

The designer escaped by bundling her into a closet before Wildenstein called the police herself only to be arrested when they saw her partner's wounds.

Klein would face the ignominy of arrest himself just days later when police accused him of pushing Wildenstein when he went back to collect his belongings.

However the bickering pair later said the headline-grabbing tussle that saw them both thrown behind bars only made them realize how much they couldn't bear to be apart.

They were reconciled as soon as authorities dropped all charges and Klein popped the question that July, presenting Wildenstein with her diamond engagement ring.
