Rocco Ritchie posed with his new mystery girlfriend as he celebrated the launch of his latest art exhibition at Frieze in London on Thursday night. 

It was a family affair as Madonna, who is set to kick off her 78-date Celebration tour at The O2 on Saturday, turned up to show her support to her 23-year-old son who has made a name for himself in the artworld. 

Rocco has quietly established himself as an expressionist painter under the name Rhed with his artwork selling upwards of £45,000. 

Rocco, whose father is director Guy Ritchie, packed on the PDA with the stunning brunette who looked effortlessly stylish in a black figure-hugging dress. 

The loved-up couple were joined by Rocco's sister Lourdes Leon, 26, and brother David Bandas, 18, as well as Stella McCartney, 52.  

As they enjoyed the family meal, Rocco's charcoal drawings could be seen framed on the wall above them.  

For his latest exhibition, Rocco turned to his mother for inspiration and drew a photo of her from the 1980s. 

Taking to Instagram, Madonna shared a series of shots of his collection before the family celebrated with dinner. 

Madonna wrote: 'Congratulations Rocco. Your show was remarkable!' 

Rocco and his new ladylove were later pictured leaving the exhibition holding hands. 

It is not known who Rocco's new girlfriend is, with the couple making their romance public at the event on Thursday.  

 MailOnline has gone to his representatives for comment. 

The exhibition is a poignant moment for Rocco as his work is being show at Frieze London over the next few weeks. 

Frieze London is one of most influential contemporary art fairs, focusing only on contemporary art and living artists, and takes place each October in Regent's Park.    

Rocco has had three exhibitions at the Chelsea art gallery, Tanya Baxter Contemporary, since 2018 and artwork listed on Artsy shows it is a lucrative business. 

A 2021 painting called Les Femme Verte is up for sale for £45,000, while 2018 art piece Stand Apart is listed at £40,000. 

Other charcoal drawings are listed as 'price on request'. 

And Rocco's portrait of his mother from when she was in the eighties could prove to be his most lucrative yet due to her fan base. 

On Thursday night, Madonna looked every inch of her Queen of Pop status in a plunging black corset and a blazer and sheer gloves as she relaxed with son David and Stella on the sofa at the event. 

Stella and the songstress have been friends for years, with the fashion designer even turning Madonna's daughter Lourdes becoming the face of her brand's scent Pop. 

The designer, who is the daughter of Beatles legend Paul McCartney, previously said to Porter Magazine of her close bond with Lourdes:  It was a massive compliment she felt safe doing that with me, because everyone and their uncle has asked her to do things.'

'It’s very funny for me, she was the one where I was like, ‘I get it, I get it, I’m there. Been there, done that, I know exactly who you are, I know exactly what you’re going through.' 

Rocco has always kept his love life quite private. Back in October last year he was pictured on a date with a mystery brunette. 

Before that he was linked to model Kim Turnbull in 2017 but they later split. 

Ritchie - who turns heads with his retro fashion sense - kicked off his career at age 17 - studying at Central Saint Martins and the Royal Drawing School and his work now sells for five figures.

Rocco's secret life as an acclaimed artist was unveiled last year by Page Six.

His bio on London's Tanya Baxter Contemporary gallery website states: 'Rhed is a young emerging artist whose cultural background is diverse and unconventional.

'His childhood was spent between New York and London which have given him an eclectic and diverse artistic background.

'Society conflicts such as the obsession with social media, fixation of celebrities & labels and generational problems such as drug abuse and depression are subjects that he approaches in a coded fashion.

'It is almost as if the artist uses the paintings to act as a spokesman for the millennial generation who have overdosed on a toxic society.'
