New love? The eye-catching sparkler certainly caught the eyes and sparked rumours of an engagement

James was clearly in his element as he enjoyed some quality time with the woman outside the restaurant as he lit up a cigarette and puffed away.  

While it is unclear what the nature of their conversation was, the ex-husband of socialite Petra Ecclestone appeared to be working his charm as he propped one arm on the wall behind the woman to casually lean closer. 

James' companion was clearly loving the attention, as she was unable to wipe the smile from her face while they continued the cosy display. 

The beauty wasn't shy about showing off her engagement finger, which sported an extremely hard to miss diamond sparkler. 

It wasn't difficult to see why she had caught the eyes of the playboy as she turned heads in her casually clad ensemble.  

She dressed her slim figure in a simple white top, which was tucked into her ankle-grazing ripped jeans in a messy manner. 

Shunning the usual high heels for a glamorous night out, the brunette opted for a pair of comfortable white trainers and toted her belongings in a chic white handbag.

Some-ring to tell us? A fancy, yellow square-cut ring, the piece of opulent jewellery dazzled in comparison to the rest of her low-key ensemble

While James has been a long-time fan of blondes - with his ex-wife being Petra and his most recent love interest, stunning Samantha Rowley - he appeared to be broadening his criteria as the woman sported glossy chestnut coloured locks. 

Sporting a glamorous coat of dewy make-up, complete with mascara laden eyes and pink gloss, James' companion looked a vision as she enjoyed the flirty night.

The pair were even spotted arriving together in James' slick black Lamborghini, with the art dealer helping her out of the car. 

James cut a trendy figure himself, opting for a navy sweater, dark wash denims and a black jacket. 

Clutching onto her phone, as well as other belongings, the stunner's enormous ring, on her wedding finger, was hard to miss.

His outing with the beauty comes after Samantha - who was reportedly in a short-term relationship with the London native earlier this year - hit back at critics of her relationship with James stating she's 'no gold digger.'

The stunning blonde said James' 'heart is as big as his bank balance' - stating: 'James has a big bank account. But he also has a big personality and a big heart.

'I'm no gold digger. The term is derogatory to women and sadly often comes from other women.'

Following initial reports of their 'engagement', Samantha was seen brandishing a huge sapphire ring on her engagement finger - which was said to be worth £1.5million.

Samantha - who recently attended the 71st annual Cannes Film Festival with pal Laura Zilli - was first photographed on James' arm just days after the final court hearing in his divorce from Petra in February.

The high-flying couple were rumoured to have been dating for several months, after being first spotted together in January.

James and his former partner Petra, daughter of Formula One's Chief Executive Bernie Ecclestone, tied the knot in at lavish £12 million wedding at a castle in Rome, Italy, in 2011.

The couple enjoyed an extraordinary life together, splashing out £100 million on a Chelsea mansion and £158 million on a 123-room home in Los Angeles, and went on to have three children.

But the marriage ended in a costly divorce battle at London's High Court last year. 

While their union didn't stand the test of time, it started off on the right note as Petra was lavished with a costly eye-catching silver engagement ring from James during his proposal.
