They have been spending considerable time together and on Thursday Rob Kardashian and his current squeeze Naza Jafarian enjoyed a day shopping and sightseeing - with Kris Jenner in tow.

The 26-year-old reality star and his new model girlfriend were seen wandering around London together and the couple didn't seem to mind the Kardashian matriarch tagging along too.

The group headed to South Molton Street in Mayfair where they headed to Browns.

The Manchester-based model left the shop carrying a large boutique bag, which could suggest that Rob might have treated his new squeeze.

Naza was dressed in a pair of jeans, knee-high boots, a printed T-shirt and a leather jacket with a fur stole around her neck.

Rob, who is trying to slim down after piling on the pounds opted for a short-sleeved black hoody and loose fitting dark trousers.

Kris wore a beige mac with studded detailing on the sleeves and a fur collar but it was her accessoires that really did the talking.

She sported a pair of beige and black Wellington boots, had a black Hermes handbag and wore a pair of gold tinted cat-eye sunglasses.

Kris couldn't resist taking a snap of her son stood in front of a red telephone box and like a true Kardashian the sock-entrepreneur posed up a storm on cue.

On Friday Rob and Kris were in Paris continuing their promotional tour for Rob's footwear accessories.

The day outing comes after Naza and Rob enjoyed a date at The Wellington Club in Knightsbridge on Wednesday night.

The 26-year-old reality star took the model out for the evening and this time he managed to leave his momanager Kris Jenner back at the hotel.

He's keen: Rob Kardashian took Naza Jafarian on a second date in two days and the pair went to The Wellington Club in Knightsbridge on Wednesday night

The pair are said to have seen each other a lot in the past couple of weeks after Rob's best friend introduced them, In Touch reports.

And it seems that the pair have more in common than at first glance - Naza reportedly previously dated Sean Phillips, who Rob's sister Khloe Kardashian was linked to when she appeared on The Apprentice in 2009.
But her past doesn't seem to have put Rob off and the pair seemed to be getting on great.

And he was even happy to introduce her to sister Kim's boyfriend Kanye West, who also joined them on the night out.

Earlier in the day Rob's new squeeze was seen wearing nothing but a sheet wrapped around her having a cigarette on a balcony in Belgravia

Naza was pictured smoking a cigarette with an unidentified blonde male friend.
The date to the swanky London nightclub came just a day after the pair enjoyed dinner at Nobu - with Rob's mother Kris tagging along too.
Rob was seen leaving the upmarket eatery with the glamorous model, who bared her legs despite the chilly temperatures in a little black dress, paired with two-tone slingbacks and a neon yellow quilted handbag.

Naz did not look dissimilar to Rob's sister Kim Kardashian, with her figure-hugging outfit and long dark curls.
She has previously featured in a campaign for Monkee Jeans, an organic denim brand.
Naz went to Manchester university and is currently signed to Nemesis model agency, although on her LinkedIn page she lists herself in the Los Angeles area, suggesting she may have met Rob closer to his home.

Rob told Us Weekly that he's starting to see results after vowing to get back in shape several weeks ago.

'I lost 5 to 7 [pounds] last week. I'm trying to lose 40,' he said during his birthday party at 1OAK in Las Vegas in March. It's a little journey, but it's good... I'm like 240lbs right now, probably 235lbs.'

The reality star admitted that he put on the pounds by eating 'a lot of great food' but has finally cracked down, motivated by 'beautiful women!'
